Durable NSF-approved LESCO poly male adapter that converts a 1" male threaded (MPT) connection to a 1/2" insert/barb. Built for compatibility with Sch 40 PVC systems, this compact fitting delivers reliable chemical resistance for pool, spa, irrigation, and potable water uses.

  • Certified for potable water: NSF-approved for safe use with drinking water and common pool and spa applications.
  • 1" MPT to 1/2" insert: Converts standard 1" male threaded fittings to 1/2" tubing or hose via the insert/barb end.
  • Sch 40 compatible poly construction: Made to work with Schedule 40 PVC and common poly components in irrigation and water systems.
  • Chemical-resistant and lightweight: Poly material resists common pool and irrigation chemicals while remaining easy to handle and install.
  • Simple installation: Push tubing onto the barb and secure with an appropriate clamp; use standard thread sealant on male threads for a leak-free connection.

This adapter is ideal when you need a compact threaded-to-hose connection for seasonal, repair, or new installations. Always confirm tubing OD, verify thread engagement, and follow local plumbing codes. For long-term outdoor use, inspect clamps periodically and replace if corrosion or wear is present.
