Do-it-yourself hose clamp. Wire clamp as the simplest way to connect hoses. How to make a wire clamp - step by step diagram

Any man has encountered the connection of a hose and a water pipe or faucet. In most cases, this is a common procedure: put the hose tightly on the pipe and turn on the water. But such a connection often lets water through, and the hose itself sometimes flies. Then comes to our aid wire clamp who can save in a problem situation.

1 Today's wire clamp– device and work

First of all, I would like to clearly define the theses: what can actually be called collars. So, this device, which is in the form of a ring, is mainly made of light metal alloys. It has a tightening mechanism in the form of a specialized nut, usually with a worm thread, and also, depending on the models, a metric thread is used on the nut. In our case, the base of the device has, as it were, a wire base, but is made of a very strong metal, which does not change when tightened.

In today's version, just a nut with a metric thread is considered to be a tightening component, when screwing which the mechanism closely fits the surface, while thoroughly pressing it on the working base. The scope of use of clamps is quite wide, but the range of action is designed to create a tight connection of hoses, rubber pipes with solid bases, branch pipes. Using a clamp, you can tightly connect the water wire of the pipes with a rubber hose and do not fear that there will be a leak somewhere.

Even the corrugated pipe for the hood is fixed with a clamp to the smoke exhauster and does not let gaseous, liquid and solid substances into the room.

Initially, this device was created just not for domestic needs, but for mechanical engineering. Clamps are an important component in the engine of virtually any car. Ask - why? But the thing is that the motor of the machine during the working period, due to vibration, is in a mobile state, and different connections, fuel supply, oils are different sections of the pipe. It is the rubber sections of the pipe that have free play, and equally vibrate simultaneously with the engine, while fulfilling their own fuel supply duties. Well, they are fixed to the metal base with clamps, they can provide a reliable, tight, and basic, high-quality connection of the main components of the motor.

2 Clamps spring wire: clips for all life occasions

Among such fasteners, I especially want to highlight one type of product: clamps spring wire, which operate on the principle of clothespins, such fasteners are entirely consistent with their own specifics. This technology allows you to install them in the direction without the use of additional tools. The design of this device is a thickened elastic wire, and quite rigid, which makes it possible for it to keep the set diameter. There are two "ears" on the edges, which make the "clothespins" function.

In order to install such a clamp at the place of operation, it is enough to squeeze the “ears” with your fingers, while the diameter of the clamp becomes larger, after which it can be put on a pipe section. That's the whole assembly process of such a multifunctional clamp. It is very likely that pessimists may doubt that such a simple device can make a dense hermetic connection. But we can assure you that the connection is quite strong and reliable, these arguments directly confirm the laws of physics. And the thing is that these devices are designed for use in places with temperature differences.

Under normal conditions, the fastening mechanism exerts its own working pressure on the connection, when heated, the metal begins to increase, thus enhancing the clamping property many times over. Such a device does not have a very large undesirable effect, in most cases, with some period, such a clamp has the feature of pinching the rubber hose, rendering it unusable. It is not best to use such fasteners in a car engine, or you can use it with further replacement.

3 How to make a wire clamp - an ethnic technique from and to

It's great when there is such a fastener in everyday life. Of course, such a thing is not needed every day, but there are times when you can’t do without a clamp, especially this can be attributed to the owners of the car. However, if you regularly forget to purchase this part for your own kit, let's try to figure out together how to make a wire clamp with the smallest set of materials and tools.

For this we will need the wire itself, which should be quite soft, but at the same time strong enough. Of the tools, a screwdriver and multifunctional pliers are useful, which can be found in virtually any home. Now let's take a step-by-step look at the whole process, which, just as you guessed, if there is a minimum of components, it will be quite simple.

How to make a wire clamp - step by step diagram

Step 1: Measure the required length of wire

First of all, let's bite off the wires as much as the diameter of our connection requires. We do not need measuring instruments, it is enough to wrap the edge of the wire around the pipe section and think about the tips for twisting, in most cases 50-60 millimeters is enough. After we fold the wire in half and bite off the excess with pliers. We bring the tips together so that they are at the same level.

Step 2: Proper Clamp Assembly

Now, when you have a wire bent twice in your hands, you need to make the correct “eye” at the place of the bend, and the diameter of the “eye” should be the same as the screwdriver, which must freely enter it. To maintain a similar size, it is enough to straighten the tips, insert a screwdriver between them and bring them together again. Of course, a Phillips screwdriver is best suited for this purpose, it is even along its entire length and does not have an increase, unlike a flat one. Next, you need to bend the resulting "eye" to the side, relative to the length of the wire, it will play the role of a lock.

Step 3: Detailed installation of a homemade clamp

You just made a wire clamp with your own hands, nothing if it is not attractive in appearance, the main thing is that it performs its own functions well. It remains to install it in its own main place and tightly twist it. To do this, go around it around the pipe section, first of all in the form in which it is, and specifically doubly, and cross the tips together. After we put a screwdriver in the "eye", we hook the second end and turn it clockwise a couple of times until a tight connection occurs. Do not forget that during the clamp you should not be very zealous, you must feel when you need to stop so that the wire does not burst. If there are very long tips left on the newly installed clamp, we advise you to bite them off with wire cutters.

It is very likely that the first time you will not be able to install a wire clamp made by yourself, maybe you will not be able to twist it, or you will overtighten it, but do not despair, you need to repeat the procedure for making the fastener again. We are sure that after several attempts you will get a good and hermetic connection, and this simple technique will always help you out in a difficult moment. Perseverance and work will grind everything! But still, for the future, keep in use a few clamps of various diameters, they will come in handy first of all!

It is literally impossible to do it with your own hands.

An improvised standard tool is also of little help.

You need to use either a specialized tool, or make something similar.

At the dawn of my career, I made hand tools for crimping hydraulic hoses with my own hands. In those days, there were no professional tools.

First you need to figure out how a hose is pressed under high pressure.

Here it is with the tip pressed in:

The photo shows the working part with a thread and already on the hose there is a sleeve (coupling) that it is that is crimped in a circle.

In the context of a fitting with an already pressed coupling, it looks like this:

The pressing process is as follows:

• the hose is cut so that the end is even.
• a coupling is put on top of the hose and sinks further.
• a nut is mounted on the nipple with the thread outward.
• the nipple is inserted into the inner part of the hose until it stops at the end of the hose.
• the coupling also returns to the stop or end of the hose.
• a special crimp is put on the coupling and squeezes it in a circle 360 ​​degrees

All processes, with the exception of the last, are done by hand and only the last is used with the use of a tool.

There are two ways to crimp the coupling without special equipment (during crimping, strong pressure must be created, since the coupling is made of a rather strong and thick material), such a coupling cannot be pulled off with clamps, and different types of pliers have an uneven shape and do not press evenly on the coupling.

1 way

To use a lathe, or rather a chuck for clamping parts, it is best to use four jaws, but you can also use three jaws. Clamp the coupling several times, scrolling it in a circle so that the pressure is even on the entire surface.

2 way

To make a crimp yourself, for this you need to carve a sleeve with an inner diameter like that of a coupling on the outside. Cut the sleeve lengthwise into 6 equal pieces. Turn a bushing with a larger diameter than the first one, drill and cut a bolt thread in six places. On the first six parts, make a notch in the center, and press the ball onto the end of the bolt.

At the first signs of pipeline depressurization, it is necessary to quickly find the damaged area and eliminate the identified defect. When performing emergency emergency work, you can use homemade clamps to stop the flow in the pipeline for a while. Ready-made clamps for fastening pipes, manufactured at the factory from stainless steel or fire-resistant plastic, are used when performing installation work on the installation of heating, sewerage, water supply, gas supply systems. These fasteners allow you to securely fix the position of pipes running along horizontal and vertical surfaces (ceilings, walls), as well as installed on special racks.

In this video, an experienced craftsman shows how to make a wire clamp:

The design of the simplest clamp

Without exception, all pipe clamps consist of a bandage - a crimping material made by manufacturers of steel, and an internal seal called a cuff. As a sealing material that seals the damaged area, they usually take special corrugated rubber, which helps prevent pipe deformation when the fixing screws are tightened. The presence of a rubber gasket in the design of the product also helps to reduce vibration and noise.

When choosing clamps, pay attention to such product characteristics as:

• inner diameter;
• bandage width;
• steel strip thickness.

The tightening range of the clamp varies depending on the size of the fastener element. The main indicators that determine the scope of its application are the strength of the connection and the level of permissible load.

Metal clamps for fastening and repairing pipes of different diameters consist of a steel frame and a seal made of corrugated rubber

Making a collar from improvised materials

Find a strip of galvanized sheet, the thickness of which does not exceed one millimeter, and a piece of three-millimeter rubber. Look in your stock for a couple of bolts (M6, M8 or M10), as well as suitable nuts and washers. Of the tools useful:

• a hammer;
• calipers;
• spanners;
• vise or pliers;
• metal scissors, which can be replaced if available with a jigsaw or grinder, equipped with appropriate cutting elements;
• drill and drills (M7, M9 or M10, M12).

Use a caliper to determine the pipe diameter. If the diameter of the pipe is large, then take the necessary measurements using a corner and a ruler. Next, cut the tin frame of the clamp in the form of a strip, the width of which should be 4-8 cm, and the length will have to be calculated. To do this, the circumference of the pipe is determined by multiplying its diameter by 3.14 (the Pi number, familiar to everyone from the school geometry course). 3-4 cm are added to the result obtained, from which “ears” are subsequently made with drilled holes for fixing bolts.

The size of the holes in the "ears" depends on the diameter of the bolts, and if the washers are wide, then you can add an extra 2-3 mm to simplify the installation of the clamp in the future. If the width of the bandage exceeds 6 cm, then it is recommended to drill holes not for two bolts, but for three. Mark a line with a marker along which to bend the “ears” at a right angle to the tin strip. This operation can be done manually if the strip is thin. With thicker material, work with a vice or pliers.

Next, the tin is bent around the pipe on which it is planned to put the clamp on, and they try to connect the ears so that the holes drilled in them coincide. If the tin does not bend well, then the strip is tapped with a hammer. A pre-cut rubber gasket, cut out taking into account the width of the bandage, is inserted into the collar.

Algorithm for installing a clamp on a pipe

Before installing the clamp, the ears are bred to the sides so that they can safely wrap around the pipe. In this case, the rubber gasket should cover the pipe defect well. If everything was measured correctly, then no more than three centimeters should remain between the ears. This distance will necessarily decrease in the process of tightening the clamp with bolts, and this process continues until it is possible to press the rubber seal against the pipe as tightly as possible.

A clamp to fix a leak in a pipe of a plumbing or heating system at home is installed at the site of damage with your own hands within a few minutes

Installation of clamps in most cases is done on a leaking pipe. Shutting off the supply of water, coolant or wastewater is not performed. Therefore, the effectiveness of the repair will be immediately visible. After wiping the pipe and bandage dry, wait five minutes and make sure that the leak has been fixed. Too long bolts, if necessary, are easily cut with a grinder or a hacksaw.

A properly installed collar can serve for several years, protecting the object from flooding. However, breaks in water supply and heating systems are desirable to weld or replace defective sections with new pipes.

Insertion into the main water supply

When connecting the water supply of a private house to the central water supply system, a mortise pipe clamp is used, which allows you to work under pressure in a short time with the help of specialized professional equipment. A clamp is installed for tapping into a pipe without pressure by a simple locksmith using a cutter and a pair of wrenches. It does not involve the use of a welding machine. In any case, these works are carried out by employees of the services serving the main water supply in the settlement, if the client has all the permits.

Stages of installing a mortise pipe clamp in the main pipeline. Clamps for tapping into a pipe simplify the work of connecting an object to central water supply systems

Now you know how to make and put a clamp on a water pipe. If the pipeline is damaged, you will be able to fix the problem yourself at least for a while before the arrival of professional plumbers.

Every man has encountered a connection between a hose and a water pipe or faucet. Usually this is a simple procedure: put the hose tightly on the pipe and turn on the water. But such a connection often lets water through, and the hose itself sometimes flies. Then a wire clamp comes to our aid, which is able to help out in a difficult situation.

First of all, I would like to clearly define the concepts: what can actually be called clamps. So, this is a ring-shaped device, usually made of light metal alloys. It has a tightening mechanism in the form of a special nut, mainly with a worm thread, and also, depending on the models, a metric thread is used on the nut. In our case, the base of the device has, as it were, a wire base, but is made of a sufficiently strong metal that does not deform when tightened.

In the modern version, the tightening element is just a nut with a metric thread, when tightening which the mechanism tightly fits the surface, while thoroughly clamping it on the working base. The scope of clamps is quite wide, but the range of action is designed to create a tight connection of hoses, rubber pipes with solid bases, branch pipes. Using a clamp, you can hermetically connect the water pipeline to the rubber hose and not be afraid that there may be a leak somewhere.

Even a corrugated exhaust pipe is attached to the chimney with a clamp and does not allow combustion products to enter the room.

Initially, such a device was created just not for domestic needs, but for the automotive industry. Clamps are an important element in the engine of almost any car. Ask - why? The fact is that the engine of the machine during operation, due to vibration, is in a mobile state, and various connections, fuel and oil supply are various pipes. It is the rubber pipes that have free play and vibrate evenly with the engine, while fulfilling their duties of supplying fuel. Well, they are attached to the metal base with clamps, they are able to provide a reliable, tight, and most importantly, strong connection of important engine components.

Among such fasteners, I especially want to highlight one type of product: spring wire clamps that work on the principle of clothespins, such fasteners are fully consistent with their specifics. This technology allows you to mount them for their intended purpose without the use of additional tools.

In order to install such a clamp at the place of operation, it is enough to squeeze the “ears” with your fingers, while the diameter of the clamp will increase, after which it can be put on the pipe. That's the whole process of mounting such a universal clamp. It is possible that skeptics may doubt that such a simple device can create a tight hermetic connection. But we can assure you that the connection is quite strong and reliable, these arguments directly confirm the laws of physics. The thing is that such devices are designed for use in places with temperature changes.

In a normal environment, the fastening mechanism exerts its working pressure on the connection, when heated, the metal begins to expand, thereby enhancing the clamping property several times. This device has a small side effect, usually over time, such a clamp tends to pinch the rubber hose, rendering it unusable. It is not recommended to use such fasteners in a car engine, or you can use it with subsequent replacement.

It is good when the household has such an element of fastening. Of course, such a thing is not necessary every day, but there are times when you simply cannot do without a clamp, especially for car owners. But if you constantly forget to buy such a part for your kit, let's figure out together how to make a wire clamp with a minimum set of tools and materials.

To do this, we need the wire itself, which should be soft enough, but at the same time quite strong. Of the tools, a screwdriver is useful and, which can be found in almost any home. Now let's take a step-by-step look at the whole process, which, as you guessed, with a minimum of elements, will be quite simple.

How to make a wire clamp - step by step diagram

Step 1: Measure the desired length of wire

First of all, let's bite off the wires as much as the diameter of our connection requires. We don’t need measuring instruments, it’s enough to wrap the edge of the wire around the nozzle and estimate the ends for twisting by eye, usually 50-60 millimeters is enough. After we fold the wire in half and bite off the excess with pliers. We bring the ends together so that they are on the same level.

Step 2: Proper Clamp Assembly

Now that you have a double-bent wire in your hands, you need to make the correct “eye” at the bend, and the diameter of the “eye” should match the screwdriver, which should freely enter it. To withstand this size, it is enough to straighten the ends, insert a screwdriver between them and bring them together again. Of course, it is best suited for such purposes, it is even along its entire length and does not have an expansion, unlike a flat one. Next, you need to bend the resulting "eye" to the side, relative to the length of the wire, it will act as a lock.

You just made a wire clamp with your own hands, nothing if it looks unprepossessing, the main thing is that it performs its functions with high quality. It remains to install it in its place of honor and tightly twist. To do this, go around it around the pipe, always in the form in which it is, namely doubly, and cross the ends together.

It is possible that the first time you will not be able to install a do-it-yourself wire clamp, you may not be able to twist it, or you will overtighten it, but do not despair, repeat the procedure for making the fastener again. We are confident that after several attempts you will get a high-quality and tight connection, and this simple technology will always help you out in difficult times. Patience and a little effort! But still, for the future, keep several clamps of different diameters on the farm, they will definitely come in handy!
