Poly Male Adaptor, 1-1/4"MPX1-1/2"Barb

Poly Male Adaptor, 1-1/4"MP X 1-1/2"Barb

The 3A114112 Poly Male Adaptor is a heavy-duty plumbing fitting designed to connect threaded pipe systems to large-diameter flexible tubing in irrigation, water transfer, and fluid distribution applications. It features a 1-1/4" male pipe thread (MPT) on one end and a 1-1/2" hose barb on the other, allowing a secure transition from rigid threaded pipe to polyethylene tubing or flexible hose. Constructed from durable nylon, this adaptor provides excellent resistance to corrosion, chemicals, and outdoor exposure, making it a reliable choice for agricultural and water management systems—because moving a lot of water requires fittings that can keep up without complaining.
