The RELIANCE WORLDWIDE PSEI3016AE is a ProLock reducing tee fitting designed for use in push-to-connect plumbing installations. Reducing tees allow a single branch point to transition between two different pipe sizes without additional adapters or soldering. This fitting is suited for residential and light commercial plumbing systems and is typically installed by licensed plumbers or experienced pipefitters working on supply lines, distribution manifolds, or branch runs.
The PSEI3016AE is used in push-to-connect plumbing applications where a main line must branch off to a smaller diameter run. Its reducing configuration makes it a practical choice for water supply distribution systems in new construction or retrofit work where pipe size transitions are required at a tee junction.
Designed as an OEM-style replacement and new-installation fitting for push-to-connect plumbing systems requiring a reducing tee configuration.
Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and depressurize the line before inserting pipe into any push-to-connect fitting. Ensure pipe ends are cut square, deburred, and fully inserted to the depth mark before pressurizing the system. Do not exceed the pressure and temperature ratings specified by the manufacturer.
