Streamline ACR Press Jaws and Ring change the game in refrigerant line installations, offering you a flame-free, efficient alternative to traditional brazing. The jaws and ring unlock productivity for HVAC system installers, eliminating nitrogen purges, combustible gases, and expensive silver solder necessary for traditional pipe connection methods. With an easy-open, in-line design, our press jaws are optimized for the tightest spaces, utilizing the M18 FORCE LOGIC Press Tool or the extended stroke M18 FORCE LOGIC Long Throw Press Tool. The Streamline ACR Press Jaws and Ring are designed for use on Mueller Streamline ACR Press fittings.
