Our 1" PEX-CRIMP Press Jaw for M18™ FORCE LOGIC™ Press Tools provide you with an easy to use solution for PEX crimp installations, eliminating the repetitive strain required with hand tools. We've optimized the 1" PEX-CRIMP Press Jaw with an easy-open, inline design for one-handed pressing when used with M18™ FORCE LOGIC™ Press Tools. These PEX crimp jaws offer the highest confidence for quality connections, as the spring-loaded opening grips the ring for precise alignment to the fitting, and a green light on our plumbing crimping tool indicates a completed crimp.
