3/4 inch x 1/2 inch x 3/4 inch Polyalloy PEX Crimp Reducing Tee – For Multi-Branch PEX Installations
The Polyalloy PEX Reducing Tee is a high-performance crimp fitting designed for transitioning between different PEX tubing sizes in potable water systems. Engineered to accommodate 3/4 inch x 1/2 inch x 3/4 inch branch configurations, this reducing tee enables streamlined routing in distribution layouts while maintaining joint integrity under pressure.
Manufactured from corrosion-resistant polyalloy, this fitting is suitable for use with ASTM F1807 or F2159 crimp or clamp connection systems. It supports long-term performance in both residential and commercial applications where dimensional reductions are needed without compromising hydraulic efficiency or compliance.
Contractor-Focused Performance Attributes
- ✅ Dimensional Reduction Allows for direct transitions between 3/4 inch main lines and 1/2 inch branch connections.
- ✅ Crimp Compatibility Engineered to fit standard PEX crimp ring and clamp tools per ASTM standards.
- ✅ Non-Metallic Composition Polyalloy body resists corrosion, scaling, and electrochemical degradation common in mixed-metal systems.
- ✅ High-Pressure Rated Suitable for continuous use in pressure systems up to 200 PSI at 73°F, per applicable PEX system design guidelines.
- ✅ Code Compliance Certified lead-free and third-party listed for use in potable water systems per NSF/ANSI 61 and 372.
