Poly Male Adaptor, 3/4"MPX3/8"Barb

Poly Male Adaptor, 3/4"MP X 3/8"Barb

The 3A3438 Poly Male Adapter is a straight nylon fitting designed to connect a 3/4" male pipe thread (MPT) port to a 3/8" hose barb, allowing threaded plumbing connections to transition directly to flexible hose lines. Constructed from durable nylon, this adapter provides reliable performance while resisting corrosion, chemicals, and environmental exposure. Its straight-through design keeps fluid moving efficiently while providing a secure hose connection—because a properly matched adapter saves a lot of time compared to trying to improvise with the wrong fittings.
