The PressACR 7/8" OD mini pressing jaw is intended for use with the PCR-20M press tool. The pressing jaw is installed in the appropriate pressing tool. When the trigger on the pressing tool is depressed a crimp is made, and the jaws must close completely to ensure a leak-free connection. When properly crimped, a unique "N" witness mark is clearly visible. Pressing tools and jaws are an integral part of ensuring a reliable, permanent connection between copper piping and NIBCO Press System fittings and valves. Use only pressing tools, jaws and chain sets that have been tested and approved for use with NIBCO PressACR fittings. Please refer to NIBCO technical data sheets and catalogs for engineering and installation information. NIBCO PressACR applies the proven performance of press technology to NIBCO air conditioning & refrigeration fittings – the most specified flow control products in the industry. NIBCO PressACR features a full range of precision engineered copper fittings, accessories, pressing tools and jaws.Features Use with PCR-20M ACR press tools Creates leak-free connections No flame, solder or flux
