Half-couplings are the same as couplings, however the length varies: for threaded pieces, it is exactly one half that of a full size coupling; for socket pieces it is slightly smaller, as the channel is elongated. As a result, only one side is threaded or socket-weld ready: the other is smooth.

We provide couplings and half-couplings in all sizes, types, and ends, in a wide range of stainless , , and other alloys.
