1 inch PEX Polyalloy Insert Coupling Crimp x Crimp

1 inch PEX PolyAlloy Crimp Coupling – ASTM F1807 Insert Fitting for Cold Expansion and Crimp Systems

The 1 inch PEX PolyAlloy Insert Coupling is engineered for joining cross-linked polyethylene (PEX) tubing in cold and hot water distribution systems. Manufactured from high-performance polymer composite (PPSU), this crimp-style fitting supports ASTM F1807 installations using copper crimp rings or stainless steel clamp rings in accordance with industry-standard tooling.

Its corrosion-resistant construction makes it suitable for both new construction and retrofit applications in residential and light commercial plumbing systems. The full-flow design ensures minimal pressure drop, while the barbed ends maintain mechanical integrity when properly crimped or clamped.

Installation Overview

Ensure tubing is properly cut, reamed, and marked for insertion depth. Use calibrated crimp or clamp tools compatible with the selected joining method. Joints must be tested in accordance with local code and system design requirements. This coupling is not suitable for use with PEX-AL-PEX or CPVC systems.

Typical Applications

Ideal for joining PEX tubing in potable water, radiant heating, and recirculation systems. Commonly used in manifold supply lines, fixture stub-outs, and mechanical chase transitions. PolyAlloy construction is especially suitable for aggressive water conditions and regions where corrosion or scaling is a concern.

Material Performance Insight

PPSU (Polyphenylsulfone) is a high-performance thermoplastic with excellent dimensional stability, hydrolytic strength, and resistance to chlorinated water. It meets or exceeds code requirements for long-term service in residential and commercial plumbing installations.

The 1 inch PEX PolyAlloy Insert Coupling delivers code-compliant performance, simplified installation, and long-term durability in systems requiring corrosion-resistant, lead-free connections. It is a critical component in modern PEX-based plumbing assemblies.
