Poly Male Adaptor, 1/2"MPX5/8"Barb

Poly Male Adaptor, 1/2"MP X 5/8"Barb

The 3A1258 Poly Male Adaptor is a durable nylon fitting designed to connect threaded ports to flexible hose lines in spraying, irrigation, and fluid transfer systems. Featuring a 1/2" male pipe thread (MPT) on one end and a 5/8" hose barb on the other, it creates a secure transition from threaded equipment ports to standard hose connections. Built from chemical-resistant nylon, this adaptor is designed to handle pressures up to 150 PSI and operating temperatures up to 120°F, making it well suited for agricultural and industrial spraying setups. It’s the kind of straightforward, dependable fitting that keeps hoses firmly attached and fluid flowing exactly where it belongs—without turning your workspace into an unintended water feature.
