1 inch PEX Engineered Plastic Insert Tee PEX x PEX x PEX

1 inch PEX Tee – Engineered for High-Performance Plumbing Systems

The 1 inch PEX x 1 inch PEX x 1 inch PEX Tee is manufactured from high-strength engineered polymer (EP), offering a durable solution for branching PEX tubing in potable water and hydronic distribution systems. Suitable for both commercial and residential installations, this tee delivers consistent, code-compliant performance in new construction and retrofit projects alike.

Product Features

• ✅ Material: Engineered polymer (EP), corrosion-resistant and non-metallic for long-term reliability
• ✅ Connection Type: ASTM F1960 cold-expansion PEX with PEX Reinforcing Ring
• ✅ Nominal Size: 1 inch x 1 inch x 1 inch PEX
• ✅ Temperature & Pressure Rating: 200°F at 80 psi, 180°F at 100 psi, 73°F at 160 psi
• ✅ Certifications: ASTM F877 / CSA B137.5 / NSF 14 & 61 / ANSI 61-G certified for potable water applications

Application Use

This tee fitting is intended for use in PEX potable water and radiant heating systems. It facilitates branch line connections in domestic water distribution, allowing for efficient layout in multi-branch piping systems. Ideal for slab, wall, and ceiling-run installations where cold-expansion fittings are required.

Installation Guidelines

Installation is performed using an ASTM F1960 cold-expansion tool with PEX reinforcing rings. Ensure tubing is properly expanded and the fitting fully inserted to allow natural memory of PEX to contract around the barbs. No adhesives, soldering, or metal clamps are required. Always verify compatibility with the system’s design temperature and pressure ratings.

Benefits for Professional Installers

• ✅ Thermal and Chemical Resistance: Non-metallic EP construction resists corrosion, scaling, and aggressive water conditions
• ✅ Dimensional Stability: Precision-molded to maintain consistent flow and eliminate turbulence at junctions
• ✅ Code Compliant: Suitable for use in systems subject to IPC, UPC, and IRC plumbing codes

Additional Notes

EP PEX fittings offer quieter operation compared to metal alternatives and reduce the potential for condensation in humid environments. Their high mechanical strength ensures a secure hold under system pressures, with minimal risk of joint failure when installed to standard.
