Stainless Steel Coupling
A stainless steel coupling connects two stainless steel pipes. If their sizes differ, the stainless steel pipe fitting is know as a reducing coupling, reducer or adapter. There are two types of couplings: slip and regular. Stainless steel couplings are highly demanded in the stainless pipe fitting market. Stainless steel couplings always help to extend or terminate pipe runs. SS couplings extend a run by jointing two lengths of pipe. Stainless steel coupling, also known as repair couplings, is without stops or ridges and they can be fixed anywhere along the pipe length for preventing leak of any kind.
Stainless Steel Union
A stainless steel union, similar to stainless steel coupling, allows the convenient disconnection of pipes for maintenance or fixture replacement. Although a SS coupling requires solvent welded, soldering or rotation, a stainless union allows easy connection and disconnection. It consists of three parts: a nut, a female end and a male end. When female and male ends are joined, the nut seals the joint. Stainless steel unions are a type of flange connector.
Stainless Steel Nipple
Stainless steel nipple is a pipe fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings. The length of stainless steel nipple is usually specified by the overall length with threads. It may have a hexagonal section in the center for wrench to grasp, or it may simply be made from a short piece of pipe. When the ends are of two different sizes it is called a reducer or unequal nipple.
