The 1436-012 Insert Male Adapter is a 1-1/4 in PVC fitting that converts polyethylene (poly) irrigation tubing to a 1-1/4 in male pipe thread (MPT). Designed for reliable outdoor irrigation and hose connections, this adapter offers a secure, corrosion-resistant joint where poly pipe interfaces with threaded fittings.

  • Material: Durable PVC construction resists corrosion and common irrigation chemicals.
  • Connection type: 1-1/4 in barbed insert to 1-1/4 in male pipe thread (MPT/MIPT).
  • Compatibility: Fits standard polyethylene (PE) irrigation tubing and common Schedule 40 or D2239/SIDR pipe sizes; use manufacturer guidance to confirm fit.
  • Installation: Barbed insert provides grip with poly tubing—use a stainless steel clamp for added security in pressurized runs.
  • Applications: Ideal for drip, sprinkler and general irrigation systems, trenching and above-ground hose connections.
  • Notes & safety: For cold-water irrigation use; not intended for hot-water or household plumbing without verifying manufacturer specifications.

Each adapter is compact and simple to install. Check local codes and manufacturer recommendations for compatibility and pressure ratings before use. Available individually or in bulk quantities—see variant SKU 1436012 for stock and ordering details.
