Union Fitting

Pipe Union is a fitting equipment that unites or connects two pipes together and they can be detached without causing any damage to the pipes. Small diameter piping connections that require a positive seal and easy assembly as well as disassembly are made with the help of union.

Union provides a leak-proof disconnection point in any PVC plumbing application and at a low cost. If a valved-disconnection point is required, use a single-union ball valve. A standard union pipe is made in three parts, consisting of :

A nut A female end A male end

When the female and male ends are joined, the nuts then provide the necessary pressure to seal the joint. Since the mating ends of the union are interchangeable, changing of a device can be achieved with a minimum loss of time.

Unions are commonly used for inserting metering and regulating devices into a piping system or for connecting piping system to vessels. There are two types of pipe unions:

Ground Joint Union Flange Union

The Ground joint union consists of three pieces. It most commonly has a brass grounding section between the two halves.
