Poly Male Adaptor, 3/8"MPX1/2"Barb

Poly Male Adaptor, 3/8"MP X 1/2"Barb

The 3A3812 Poly Male Adaptor is a durable nylon fitting designed to connect threaded components to flexible hose lines in spray, irrigation, and fluid transfer systems. With a 3/8" male pipe thread (MPT) on one end and a 1/2" hose barb on the other, it provides a secure transition from threaded ports to standard hose connections. Constructed from chemical-resistant nylon, this adaptor is built to handle pressures up to 150 PSI and operating temperatures up to 120°F, making it a dependable choice for agricultural and industrial spraying setups. It’s the kind of small fitting that quietly keeps everything connected—because when hoses and threads cooperate, the whole system behaves a lot better.
