1/2 Inch x 1/2 Inch x 3/4 Inch PEX Polyalloy Reducing Insert Tee – Durable Transition Fitting
The 1/2 inch x 1/2 inch x 3/4 inch PEX Polyalloy Reducing Insert Tee is engineered for transitioning between varying pipe sizes in potable water distribution systems. Manufactured from high-performance polyalloy, this tee provides dimensional stability, chemical resistance, and long-term performance in PEX installations requiring mechanical crimp connections.
Key Applications
This reducing tee is commonly utilized in:
Branching circuits in PEX water supply lines
Retrofitting systems requiring mixed line diameters
Cold and hot water service connections in residential and commercial buildings

Installation Notes
Compatible with PEX tubing and secured using copper crimp rings or stainless steel cinch clamps with ASTM F1807 or F2098 tools. Proper insertion depth and uniform crimping are essential to ensure a pressure-tight seal. Always verify system compatibility and conform to applicable plumbing codes.
Material Advantage
Polyalloy (PPSU) provides impact resistance and dimensional stability under thermal cycling. It is widely accepted in both chlorinated and non-chlorinated water systems, maintaining long-term mechanical integrity without the galvanic corrosion risks of metal fittings.
The 1/2 inch x 1/2 inch x 3/4 inch PEX Polyalloy Reducing Insert Tee is a dependable solution for PEX system branching, offering superior strength and compliance with modern potable water system requirements.
