Uponor a4160500 Compression Ring 1/2 Inch

Product Description

The UPONOR a4160500 is a 1/2 inch spare compression ring designed for use with UPONOR QS20 PEX fitting assemblies. This replacement ring restores the mechanical seal within a compression-style PEX connection, allowing a licensed plumber or radiant heating technician to service an existing fitting without replacing the entire assembly. The compression ring seats against the fitting body to create a watertight joint when the fitting is properly tightened. Keeping spare rings on hand reduces service call time when a fitting needs to be broken down and reassembled during a repair or system modification.

This compression ring is suited for residential and light commercial plumbing and radiant heating applications where UPONOR QS20 compression fittings are installed on 1/2 inch PEX tubing. It is a spare component intended for technicians already working with the UPONOR QS20 fitting system who need to replace a damaged or worn compression ring in the field rather than sourcing a complete fitting.

Key Features

• Sized for 1/2 inch PEX tubing connections

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor familiar with PEX compression fitting systems. Shut off the water supply and relieve system pressure before disassembling any fitting. Inspect the fitting body for damage before installing the new compression ring. Follow all applicable local plumbing codes and the fitting manufacturer's assembly procedures to ensure a proper seal.
