The Dixon SM250F pin-lug adapter connects a 2-1/2-inch male NPT pipe end to a 2-1/2-inch female NST (NH) swivel hose connection. The adapter is cast brass.
The female swivel lets you tighten the hose-side connection without rotating the installed male pipe end. Check both mating connections before ordering: the pipe side requires female NPT, while the hose side requires male NST (NH).
