1/2 inch x 1/2 inch x 3/4 inch PEX Polyalloy Reducing Insert Tee Crimp x Crimp x Crimp

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

Technical Specifications

• Connection Type: ASTM F1807 Crimp (insert/barbed)
• Material: PPSU (polyphenylsulfone/polyalloy) – lead-free and corrosion-resistant
• Dimensions: Inlet 1/2 inch x Outlet 1/2 inch x Branch 3/4 inch
• Operating Temperature: Up to 200°F (93°C)
• Pressure Rating: 160 PSI at 73°F, 100 PSI at 180°F, 80 PSI at 200°F
• Certifications: NSF/ANSI 61, NSF 14, ASTM F877, CSA B137.5, and compliant with U.S. Safe Drinking Water Act

Performance Characteristics

• Resists Chlorine Degradation: Suitable for municipal water applications
• Non-metallic Construction: No dezincification or corrosion concerns
• UV-Stable Packaging: Ensures shelf integrity prior to installation

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.
