Schedule 80 CPVC Unions
Sch 80 CPVC unions are similar to couplings in that they join together two pieces of CPVC pipe. Unions, however, are designed to allow the user to disconnect the joint after installation for maintenance or repair. Unions use two ends that connect to the surrounding pipe line and two threaded ends that join together in the middle using a union nut.
These are made entirely of CPVC material and are an excellent choice for pipe installations that may need to be altered down the road. CPVC unions are light gray and come in either socket or female threaded ends (FPT).
Note: if you are replacing part of an existing union, be sure to replace with the same brand and style. Unions of different brands are usually not compatible.
