Mr Pex 2410625 Pex-al-pex EK20 Loop Fitting 5/8 Inch

Product Description

The MR PEX 2410625 is a brass compression fitting assembly designed to connect 5/8-inch PEX-AL-PEX tubing to manifolds and transition fittings that use EK20 connections. Each assembly ships complete with one nut, one insert, and one brass compression ring, so no additional hardware is needed for the connection. Rated to 200 psi and 200 degrees F, this fitting is built for residential and light commercial hydronic heating loops where reliable, leak-free joints are essential. The brass construction meets ASTM F1960, ASTM F877, and NSF standards, making it suitable for potable and heating system applications.

This fitting assembly is used in hydronic radiant heating systems where PEX-AL-PEX tubing terminates at a manifold with EK20 port connections. It is a common component in floor heating and panel radiator loop installations. Licensed plumbers and hydronic heating technicians install this fitting as part of loop-to-manifold connections in both new construction and retrofit heating projects. The EK20 female thread interfaces directly with compatible MR PEX manifolds and EK-style transition fittings.

Compatibility

Designed for use with MR PEX PEX-AL-PEX tubing in the 5/8-inch size. Compatible with MR PEX manifolds and transition fittings equipped with EK20 connections. Fitting system compatibility is limited to PEX-AL-PEX compression systems.

Installation Notes

This fitting is installed by licensed plumbers or hydronic heating technicians. Shut down and depressurize the heating system before making or breaking any connections. Use appropriate compression tooling for PEX-AL-PEX fittings and verify all joints are fully seated before returning the system to pressure. Follow applicable local plumbing codes and manufacturer torque guidance when tightening the compression nut.
