The PEX Crimp Jaws for M18™ FORCE LOGIC™ Press Tools provide an easy to use solution for PEX crimp installations, eliminating the repetitive strain required with hand tools. With an easy open, in line design, the jaws are optimized for the tightest spaces, utilizing the M18(tm) FORCE LOGIC(tm) Press tool, or the extended stroke M18(tm) FORCE LOGIC(tm) Long Throw Press tool. 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 the press tool indicates a completed crimp. Compatible with F1807 & F2159 Connections.
