Which version do I need? We also carry a similar model with a different specification. Compare size, connection, length and the other details before ordering, and contact us if you need help choosing. See also: Sioux Chief 645WG3P 3/4" F1960 x 3/4" PVC Adapter.

Sioux Chief 645WG3 is a 3/4" x 3/4" PEX F1960 coupling in no-lead (NL/DZR) brass.

Use it to join two lengths of PEX tube or to repair a damaged section of line. F1960 joints are cold-expansion connections: the tube is expanded, the fitting inserted, and the PEX shrinks back onto it. With PowerPEX Type-B tube, Sioux Chief recommends a self-rotating power expansion tool.

Match the connection standard (F1807 crimp, F1960 expansion or F2159 poly crimp) to the PEX tube, rings and tools already on the job before ordering.
