The NIBCO Press System® pressing chain adapter jaw is intended for use with 2-1/2-inch, 3-inch and 4-inch chains. The pressing chain adapter jaw is used to compress the chain around the fitting, and maintain proper pipe alignment and uniform crimp. Once secured to the fitting, the chain will not fall off before it is crimped, but yet is easily removed after the crimp is made. 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.
