JG ProLock™ fittings use a collet with stainless steel teeth that grips the pipe when fully inserted and an O-ring to provide a permanent, leak-proof seal. When twisted into place, the locking cap locks the pipe in place and creates an audible click, ensuring maximum security. No tools, soldering, clamps or glue are ever required.
Approved for behind-wall use
For use with copper, PEX and CPVC
Twist-to-lock technology provides added security
Suitable for hot & cold potable water and hydronic heating applications
