This 3/4" MPT x 1" PVC reducing male adapter converts a 3/4" male pipe thread to a 1" barbed insert for polyethylene tubing. Molded from schedule 40 PVC, it provides a reliable transition between threaded equipment and 1" ID poly tubing for irrigation, potable water, and general plumbing applications.

  • Connection: 3/4" Male Pipe Thread (MPT) to 1" barbed insert (fits 1" ID poly tubing).
  • Material & Standards: Schedule 40 PVC construction; meets ASTM D2609 and is NSF 14/61 certified for potable water use.
  • Performance: Lead-free, corrosion-resistant PVC with a typical maximum temperature rating near 140°F and rated for typical irrigation pressures.
  • Installation: Use Teflon thread seal tape on the MPT end and secure the barbed insert with a worm-gear or stainless hose clamp for a leak-resistant connection.
  • Applications: Ideal for irrigation mainlines, pump and filter outlets, landscape systems, and cold-water plumbing where a threaded-to-poly transition is required.

This adapter is a compact, single-piece solution that eliminates extra fittings when reducing from a smaller threaded outlet to larger-diameter poly tubing. Verify thread type and tubing I.D. before installation. Do not use for compressed air or gases; follow local plumbing codes for potable water systems.
