Large Diameter Elbow Pump Fitting
The Watts AquaLock large diameter elbow fitting provides a secure, leak-free right-angle connection for pump assemblies and space-constrained installations. Push-to-connect design works with copper, CPVC, PEX, and all polyethylene tubing types without tools or thread tape.
Universal Tubing Connection
AquaLock fittings connect to copper, CPVC, PEX, LDPE, MDPE, HDPE, and polypropylene tubing. Match tubing size to fitting specification: 3/8" OD polypropylene corresponds to 1/4" copper tube size (CTS), 1/2" OD to 3/8" CTS, 5/8" OD to 1/2" CTS, 7/8" OD to 3/4" CTS, and 1-1/8" OD to 1" CTS. For NPT threaded connections, use national pipe tapered thread standards where 1/4" NPT measures 0.540" OD actual, 3/8" NPT is 0.675" OD, 1/2" NPT is 0.840" OD, and 3/4" NPT is 1.050" OD actual diameter.
