Fittings for PE-Xa and PE-RT pipes

The ICMA Article 110 fitting is a brass compression adapter designed to connect PE-Xa and PE-RT tubing to hydronic manifolds and heating components. The fitting consists of a nickel-plated union nut, compression ring, and brass insert with dual O-rings that provide a secure, leak-resistant connection. Designed specifically for radiant floor heating and snow-melting systems, these fittings simplify installation while ensuring reliable sealing and long service life. Available in 1/2 in and 3/4 in sizes, they are compatible with ICMA manifold systems and other equipment using standard threaded manifold connections.

Usage

These fittings are used to connect PE-Xa and PE-RT tubing to hydronic manifolds in radiant floor heating and snow/ice melting systems. The fitting inserts into the pipe while the compression ring and union nut securely fasten the tubing to the manifold's threaded outlet, creating a dependable mechanical seal without soldering or welding. They are commonly installed on distribution manifolds supplying multiple heating loops in residential and commercial hydronic systems.
