Pipe Union is a type of fitting equipment designed in such a way to unite two pipes that can be detached without causing any deformation to the pipes. Any kind of small diameter piping connections requiring a positive seal and easy assembly as well as disassembly is made with the help of pipe union. In other words, the pipe unions can disjoint two pipes very easily. They are widely demanded in the pipe fitting market.


Materials used:

Stainless steel

Malleable iron








Rubber etc.

Buyer's guide

Important features that buyers should look for:






Easy to install

Corrosion resistance

Three parts of pipe union:

A pipe union consists of three parts – a nut, a female end, and a male end. To make an effective working pipe fitting, both the male and female ends are sealed together with the help of nuts. A female threaded fitting has threads on the inside, while in the male-threaded fitting, the threads are on the outside. As the pairing ends of the union can be interchanged, these pipe fittings can be easily changed in a short span of time.

A nut

A female end

A male end

With the joining of the female and male ends, the nuts are used to provide the necessary pressure to seal the joint.

Pipe UnionThe parts of the pipe union are normally locked together by at least one radial screw or nut with a sized cross-section. When severe pulling stress is applied onto the pipe union from the outside, the locking screw breaks and removes the two parts of the union, which in turn separates together with the pipes to which they are attached. Under normal conditions elastically stressed sealing objects ensure the maintenance of water tightness between the union parts.

Advantages of pipe union:

There are various advantages of pipe unions like:

To provide a leak-proof disconnection point in any piping system.

Used for inserting metering and regulating devices into any plumbing application.

Can connect the piping system to vessels.

Can join two pipes of different sizes together.

Can easily remove the join between two pipes.

Easy to install.
