Uponor Q4691500 Ring with Stop 1-1/2 in Pex

Product Description

The UPONOR Q4691500 is a 1-1/2 inch PEX ring with stop, manufactured from polyethylene for use in PEX piping systems. The integrated stop ensures consistent insertion depth during connection, reducing the risk of incomplete engagement when joining PEX tubing to fittings. This ring is installed by licensed plumbers and hydronic heating technicians working on radiant, potable water, or mechanical piping systems where PEX tubing is the specified pipe material.

This ring with stop is suited for residential and light commercial plumbing and hydronic applications using 1-1/2 inch PEX tubing. It is used during fitting assembly to maintain proper tubing position before the expansion or crimp connection is completed. Installers working on manifold systems, radiant floor heating loops, or domestic water distribution will encounter this part as a standard component in the fitting assembly process.
