Swage Nipples Definition:

A pipe nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe fittings. It is a connector or a coupling threaded on both ends. PBE Pipe nipples are used to allow plumbing to be connected to a water heater or other plumbing. They are used to fit straight end hose or pipe. A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam.

Swage nipples are often used in small diameter pipe systems, and are similar to butt weld reducers. They are concentric and eccentric available, with various ends. The most common types are:
