COMPATIBILITY & APPLICATIONS

Tubing & Pipe Materials

AquaLock fittings connect securely to copper, CPVC, PEX, LDPE (low-density polyethylene), MDPE (medium-density polyethylene), HDPE (high-density polyethylene), and polypropylene tubing. Ideal for potable water lines, RO system plumbing, inline filter installations, ice maker connections, and retrofit projects where soldering or threading is impractical. The large diameter barb design accommodates higher flow rates in whole-house filtration, commercial beverage equipment, and municipal water distribution applications.

💧 Pro Tip: AquaLock push-to-connect fittings eliminate the need for torches, flux, and thread sealant. Cut tubing square, deburr the end, and push firmly until seated. The internal stainless steel grab ring locks the tube in place while the O-ring seals against leaks.
