Rls 399021151040 Copper Press Jaw 1/4 Inch 15 Kn

Product Description

The RLS 399021151040 is a 1/4 inch refrigerant-grade copper press jaw rated at 15 kN, designed for use with Klauke press tools. This jaw creates leak-free connections on copper refrigerant lines without flame, brazing rod, flux, or nitrogen purge. It is engineered to work with RLS Braze-Free press fittings, allowing HVAC technicians to complete refrigerant piping connections in seconds. The flame-free process eliminates the need for hot work permits and fire spotters, reducing jobsite risk and speeding up installation workflows on both residential and commercial refrigerant systems.

This press jaw is suited for HVAC and refrigeration contractors installing or servicing split systems, mini-splits, rooftop units, and other refrigerant-piped equipment. It is intended for use on 1/4 inch copper refrigerant tubing in applications where speed, safety, and repeatable connection quality are priorities. Installation teams working in occupied buildings, data centers, or other fire-sensitive environments benefit most from the no-flame approach this jaw enables.
