3/4 in. x 1/2 in. x 1/2 in. PEX Engineered Plastic Reducing Insert Tee – Cold Expansion Fitting for Potable Water Systems
The 3/4 inch x 1/2 inch x 1/2 inch PEX Engineered Plastic Reducing Insert Tee is a multi-size transition fitting designed for use in cold and hot potable water distribution systems using PEX-a tubing and cold expansion connection methods. Manufactured from high-performance engineered polymer, it offers corrosion resistance and dimensional stability in residential and commercial applications.
Field-Ready Characteristics
✅ Precision-Molded Insert Barbs – Ensures a secure, full-surface engagement with PEX tubing when used with approved expansion rings.
✅ High-Performance Polymer – Formulated to meet durability and pressure requirements in potable water systems; resistant to mineral buildup and chemical degradation.
✅ Lead-Free Compliant – Meets NSF/ANSI 372 and complies with the Reduction of Lead in Drinking Water Act for installations requiring certified low-lead components.
Installation Considerations
Designed for use with ASTM F1960 cold expansion fittings and expansion PEX-a tubing. Always use manufacturer-approved tools and ensure proper expansion and full insertion before pressure testing. This tee does not require solder, glue, or threading, reducing time and labor on site.
Application Scope
Used for branching off 1/2 inch lines from a 3/4 inch main in multi-port manifolds, fixture drops, and retrofit conversions. Commonly specified in plumbing systems where space efficiency and non-metallic components are preferred—especially in areas prone to corrosion or where grounding concerns exist with metallic fittings.
Regulatory Compliance
All fittings are certified for use in potable water systems and conform to applicable IPC and UPC code requirements. Third-party tested to NSF/ANSI 14 and 61 standards.
✅ Multi-Diameter Adaptability – Enables downsizing from trunk to branch lines with minimal flow disruption.
✅ Non-Corrosive Composition – Ideal for installations in high-humidity environments or chemically treated water systems.
✅ Compact Profile – Allows for dense manifold configurations and simplified in-wall installations.
This reducing insert tee is built to support long-term system integrity in modern water distribution networks. Its molded design and code compliance make it a dependable solution for contractors working with expansion PEX systems.
