Watts AquaLock - Large Diameter Reducing Stackable Tee
Large Diameter Reducing Stackable Tee
The Watts AquaLock Reducing Stackable Tee lets you branch your water line with different tube diameters at each connection point, using the same push-to-connect technology trusted by installers across North America. Compatible with copper, CPVC, PEX, and polyethylene tubing, this fitting eliminates the need for soldering, crimping, or threaded adapters in tight spaces behind RO systems, under-sink filters, and manifold assemblies.
AquaLock fittings accept copper, CPVC, PEX, LDPE, MDPE, HDPE, and polypropylene tubing. The push-to-connect collet grips securely on contact, and the internal O-ring creates a watertight seal rated for residential and light commercial pressure. Use the polypropylene OD to copper CTS conversion chart when connecting dissimilar materials: 3/8" OD polypropylene matches 1/4" copper tube size, 1/2" OD matches 3/8" CTS, 5/8" OD matches 1/2" CTS, 7/8" OD matches 3/4" CTS, and 1-1/8" OD matches 1" CTS.
