2 inch Pool Pump Union
2IN UNION SKT (SOCKET) (SLIP) X MIP (MTP)(MALE THREADED PIPE) - CPVC
2in CPVC union with large oring seals up tightly on both sides of your pool pump, filter or heater. Having unions on the equipment allows for movement of the equipment, for service, storage or inspection and prevents the problem of continuous fitting replacements. If these threads shrink in the future (although CPVC is heat resistant), you can just replace the threaded half, and re-use the tailpiece and nut. 2in union is SKTxMIP (slip x threads) to fit 2 inch pumps, heaters and filters.
