This PVC insert reducing male adapter provides a secure transition from 1-1/2" pipe to 1-1/4" pipe using a male NPT thread on one end and a barbed insert on the other. Designed for use with polyethylene pipe, the fitting offers reliable, corrosion-resistant service for irrigation, potable water, and general purpose piping systems.

  • Durable PVC construction: Manufactured from rigid PVC for chemical resistance and long service life.
  • Connection types: Male NPT (MIPT) threads on the large end and barbed insert on the small end for secure polyethylene connections.
  • Size: 1-1/2" x 1-1/4" nominal pipe sizes (reducing adapter).
  • Standards & certifications: Conforms to ASTM D2609; NSF 14 and NSF 61 certified for potable water applications.
  • Operating limits: Rated for typical irrigation and potable systems; service temperature up to about 140°F and working pressures commonly up to 200 psi (consult system specifications).

Ideal for irrigation and polyethylene pipe installations where a threaded connection is required on one end and a push-in polyethylene connection on the other. The barbed insert is designed to grip polyethylene tubing—use an appropriate stainless-steel clamp for a leak-proof joint where required. Compatible with Schedule 40 and D2239/D2104 polyethylene pipe where insert fittings are specified.
