Full coupling

A full coupling is a straight forged fitting with two connection ends used to join two aligned piping sections. Full identifies a two-ended coupling body in contrast with a one-ended half coupling, rather than merely describing length. The product name does not resolve the connection method: forged full couplings may be offered in threaded or socket-weld forms, so the required form must be stated in the order. Selection should verify both end types and standards, size and any reduction, material, sealing or welding method, alignment, and future disassembly needs.
