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. *Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.
Stainless pipe fittings for improved strength & lower carbon content for greater resistance to corrosion.
Union connectors separate into three pieces so you can access your line without unthreading pipe connections.
