The NIBCO® Press System® 3/4-inch standard pressing jaw is intended for use with the PC-280 press tool or the PC-100 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, jaws and chain sets 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 Press System® fittings and valves. Please refer to NIBCO technical data sheets and catalogs for engineering and installation information. NIBCO Press System® applies the proven performance of press technology to NIBCO valves and fittings – the most specified flow control products in the industry. The NIBCO Press System® features a full range of precision engineered copper and copper alloy fittings, commercial valves, accessories, pressing tools, jaws and chains.
