Female Unions

The 150 PSI union pipe fitting has three pieces and includes a threaded connection that can be screwed or unscrewed to connect or disconnect pipes more easily than couplings. It features NPT threads on both ends which create tighter seals than straight threads. This class 150 fitting meets standards ISO 9001:2008 and ANSI B1.20.1 for quality assurance. *Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.
