How To Seal Brass Water Fittings

How To Seal Brass Water Fittings. Water needs a medium to travel in your house. So, for this reason, we use pipes to provide them with a medium.

But the pipes need to be fixed so that they can travel without a problem. Thus, brass fittings are installed.

They need to be installed properly and connected firmly such that no leakage occurs. So, if we want to install fittings, we need to know the way to seal them.

The brass fittings after being placed are tightened by screws, but before that, we use tape or other material to wrap around it. This aids in stopping the water from exiting through the fittings.

Proper sealing needs to be done with a proper method such that we do not face a problem. Thus, in the article, steps are stated.

How To Seal Brass Water Fittings

They are to be sealed using special plumbing tape. The tape, when used, takes the form of thread and is tied around the pipes.

Then a solution is applied to the tap. The solution is properly spread, making sure that it is used equally all around.

Then the pipe is inserted into the fitting. Then, a lubricant is applied to it. There can be screws or nuts on it. Those screws or nuts are to be tightened properly such that they are not loose.


Certain things are needed and requirements are to be met for this.

  • Pliers
  • Wrenches
  • Plumber tape
  • Teflon compound
  • Supply tubes
  • Gloves
  • Mask
  • Damped clothes


After acquiring the above materials and completing the requirements, let’s start with the steps.


The pipes and the other materials might carry germs or prove harmful to you in some other case. To prevent this, it is better to wear gloves and a mask and also be doing the things carefully.

Not just for ourselves, but so that the materials and pipes are not damaged either.


After you have completed the step of safety. Then you need to take out the pipes that you are to join or fit together. Then take a pipe and star taping the part with the curves that are to be inserted into the fittings.

Tape the pipe firmly such that the tape is not loose and can be inserted. Apply a limited amount, such that you do not overdo it.

Applying compound

The compound you have is now to be applied. The pipes should be properly taped before this. After taping the pipes, you just need to put some compound on the taped area. Then you need to spread it all around the area.

Make sure the spread amount is not uneven. The uneven spread will be a problem in the fitting of the pipes.

Joining the pipes

The pipes are now to be inserted into the joints. They should be inserted and then turned so they go more in. Then, using the wrenches, tighten the pipes such that they are completely attached and are unable to move just by hand.

The points you inserted into the pipes are supposed to be the taped ones and the ones you have applied the compound on.


The ferrule and the brass joint are then to be applied with the compound as well. Like above, spread the compound properly and evenly for it to work properly.


Then apply or tie the thread around the pipe such that the thread is tight. The thread should be on the rings so that the rings are almost covered.



Then tighten the brass, fitting around so that the pipes are properly fixed. The nuts should be tightened with the wrenches as before.

Then fix all the joints like that and make sure that none of them is leaking. You can test it by turning the water on.

A useful tip is that you do not need to use the tape if you are using a gasket or a rubber seal.


Sealing of the brass pipes or fittings should be done properly, as they are to prevent leakage in the house or the installed place. The steps might not be different if you are using any other material instead of brass.

You can also use other materials for sealing. But be sure to perform your task properly.
