Our 5/8" RLS® Press Jaws are designed to press RLS® HVAC/R Braze-Free Press Fittings and optimized for MILWAUKEE® M18™ FORCE LOGIC™ Press Tools. A flame-free alternative to traditional brazing, these RLS press jaws offer you up to 60% faster connections when installing high-pressure HVAC and refrigeration systems. The RLS® Press Jaws eliminate the need for nitrogen purges, combustible gasses, and expensive silver solder necessary for traditional methods. We've optimized the press tool jaws with an easy-open, inline design for one-handed pressing when used with M18™ FORCE LOGIC™ Press Tools, the smallest, most intelligent Milwaukee® press tools.
