As long as pipes are used in plumbing, there are plugs on them. These details are usually given undeservedly little attention, but they are also part of the tightness of the entire pipeline and must clearly perform their functions. In this article we will look at their main types and purposes.

Pipe plug: selection, installation and removal on your own
Pipe plugs can be used for a wide variety of purposes. They are most often used for the safe transportation of pipes, to prevent leaks, and also as decorative elements. What types of plugs there are and how to choose a device that meets certain requirements, read on.
Fittings for temporary or permanent closure of various pipes
Selection of stubs
The choice of plugs should be based on several factors:
- type of fitting;
- selection of the material from which the plug is made;
- rules of application.
What types of stubs are there?
First of all, the classification of plugs is carried out according to the material from which the devices can be made. The following materials are used:
- Metal. The most popular are plugs made of steel and brass. The metal pipe plug is strong enough, so it can be used for gas, water and sewer pipes. The only drawback is susceptibility to corrosion.
Fitting made of brass
- Plastic and polyethylene. Such fittings are not subject to corrosion, but can become deformed when exposed to high temperatures and sunlight. The plastic plug is not very expensive and can be used as an internal plug for pipes.
Pipe fitting made of plastic
- Chromed metal. The plug made of this material is the most expensive. It is practically not subject to corrosion. Mainly used as a decorative element. For example, plugs for fence pipes.
Decorative element for pipes made of chrome steel
- Rubber. Rubber pipe plugs are used to protect pipelines from dirt and debris. As a rule, they are not used as holding elements, since they are very plastic and cannot be securely fastened.
Purpose
Plugs are used in the following situations:
- During pipe transportation . This helps prevent the product from receiving internal damage.
Handling pipes with end caps
- To block the end of a branch of a water supply, sewer or gas pipeline . After all, all pipelines must end somewhere, and it is the plug that is responsible for the necessary sealing of such a place.
Plastic plug for sewer pipe
- When repairing a damaged area . Especially if it is impossible to shut down the entire system, but it is necessary to isolate the recovery site by stopping the flow of the pipeline contents.
Replacing brake pipes. Important points!
But to be honest, there was a situation: I waited until the ordered parts were delivered, during which time I turned off the brakes of both rear wheels and drove CAREFULLY for a week. Both wheels need to be turned off (although I also had a problem with the right rear). Replacing brake pipes. Useful tips! https://youtu.be/UNJteTLdH5Q In this video I tried to tell and give some useful tips on replacing brake pipes using the Passat B3 car as an example. But all this applies to other cars. Let me remind you that you should not wait for the brake pipe to become very rusty and burst. Inspect the brake pipes in a timely manner and replace them with new ones if required. Do not wait for the brake pipe to burst at the “hour X”.
Fitting selection criteria
The plug is selected according to several parameters:
- Material of manufacture. As a rule, PVC fittings are used for metal-plastic pipes, polyethylene for PET, and steel or brass for metal. Rubber ones are used as temporary ones.
- Diameter, size and shape. The cross-section of the plugs must exactly match the parameters of the communication pipes. In addition, round fittings are used for round elements, and square fittings are used for profile elements.
- Purpose. For long-term sealing of the pipe, it is better to buy a threaded or elliptical fitting. If the plug is installed for a short time, it is better to use a flange one. Moreover, it is not recommended to buy rubber and polymer plugs for the hot water system or heating pipes. They change their shape when exposed to high temperatures. As a result, system depressurization may occur. Pneumatic and threaded plugs are not installed on gas pipelines. It is better to use flanged ones here.
Decorative plugs are made from PET in various shades. The color is added to the polymer at the casting stage. The fitting is painted uniformly throughout the entire thickness of the plastic.
Without threading
Without threading
There are situations when threading a metal water conduit is impossible. For example: you replace an emergency tap in an apartment, but it simply falls off along with the rusted threads on the pipe. The remaining piece (a piece of pipe) does not make it possible to re-cut the thread with a die, there is simply not enough space. The only way out is welding, but it simply may not be at hand, and welding work in an apartment is still a pleasure.
I had this situation too, so I offer my own solution to the problem.
For work you will need materials:
- Coupling with external (internal) thread for propylene pipes of a suitable diameter.
- Clamp clamp (as in the picture below).
From the tools:
- Bulgarian
- Electric hair dryer
- A hacksaw or just a hacksaw blade

Installation:
We cut the pipe evenly, chamfer it along the outer diameter of the pipe, using a grinder or a metal file, if it is not possible to get close with a grinder.
We put the clamping clamp on the pipe, make transverse cuts and grooves on the pipe using a hacksaw. This will contribute to a more reliable clutch grip.
We warm up the pipe as much as possible with an electric hair dryer and immediately proceed to warming up the inside of the landing coupling until characteristic softening. Then we quickly seat the coupling on the pipe until it stops. We put on the clamping clamp, and until the coupling has lost its elasticity as much as possible, but without fanaticism, we compress the coupling, tightening the adjusting screw.
We wait for it to cool completely, screw the plug onto the coupling and supply water to check the working pressure; if the coupling does not leak, then your installation was successful.
At the time of writing, couplings mounted in this way are three years old.
Attention!
It should be noted that such a solution should be applied as a temporary measure. The problematic plumbing system should be replaced with a new one using modern materials.
Happy installation!

How to get home if the brake pipe bursts. manipulator Nissan diesel
I started to put everything together when the brake pipe burst. Well, nothing, it was lying somewhere in stock, I began to slowly unscrew it when the brake line burst a little further on.
On the road, the brake pipe burst, and every time the brake pedal was pressed, the fluid leaked out... It was decided to plug the brake pipe - but alas, in vain! Because the pressure is too high, and the tube is rusty..! Another solution turned out to be more practical. Having removed the brake fluid supply hose from the reservoir to the pg, we turn off the rubber hose by inserting a 10mm bolt into it. and tighten it with a clamp so that the bolt does not fly out. And that’s it, you can drive, but carefully, keeping your distance because... The rear brakes don't hold up. PS God forbid that you don’t need this... but maybe it will help someone..!

Has the brake pedal become wobbly? Broken brake hose? There is a solution!
It just so happens that instead of notes about the desired tuning and modifications to my bus, my entire BZ is filled with articles about repairs. This time there was another breakdown, the rear brake pipe burst. The breakdown could not be repaired immediately, as it burst almost behind the tank. I turned off the circuit on the rear right wheel and drove it like that for 3-4 months. Yes, it’s true that safety comes first, but the car runs every day and there was no time for repairs. Fortunately, the completed technical inspection came to my aid, and I can’t drive without it. The New Year holidays passed, and then I found time to repair my bus. What to do if your brake hose suddenly bursts?
