Universal Tubing Systems
AquaLock fittings connect to copper, CPVC, PEX, LDPE, MDPE, HDPE, and polypropylene tubing. Match the outside diameter of your tubing to the appropriate CTS (copper tube size) rating for proper fitment. No need to match materials—these fittings bridge different tubing types in the same assembly.
