CertainTeed PC150 Municipal Pipe Restrained Joint Coupling

CertainTeed PC150 Certa-Lok R/J 10" Municipal Pipe Restrained Joint Coupling is a 10-inch, non-metallic joint accessory from CertainTeed’s Certa-Lok line designed to connect two PVC pipe lengths in municipal piping systems. The RJ designation identifies it as a restrained joint, providing enhanced resistance to joint movement under internal pressure and external loads, with the PC150 rating indicating a 150 psi pressure-class suitability for typical municipal service. This coupling employs the Certa-Lok locking system to join pipe bells without external bolts, delivering a secure, leak-tight joint through its groove-and-spline engagement and integrated sealing elements. Intended for municipal applications, this 10" PC150 RJ coupling supports reliable underground water distribution work and related piping networks.
