Durable PVC insert reducing coupling for joining 3/4" to 1/2" polyethylene or flexible hose. The barbed insert ends provide a secure, leak-resistant connection when used with stainless steel or worm-gear hose clamps. Ideal for irrigation, potable water, and general-purpose fluid transfer.

  • Part number/SKU: 1429101; size: 3/4" x 1/2" (Insert x Insert).
  • Material: rigid PVC, injection-molded for consistent dimensions and corrosion resistance.
  • Standards: meets ASTM D2609 and is NSF certified for potable water applications (NSF 14, NSF 61).
  • Compatibility: designed for use with polyethylene pipe (ASTM D2104/D2239), vinyl, rubber, and other flexible hose types.
  • Performance: schedule 40/STD compatible; engineered for typical irrigation pressures and temperature ranges up to 140°F.
  • Installation: push the pipe onto the barb and secure with an appropriate clamp; do not use for compressed air or gases.

Compact and reliable, this reducing coupling simplifies repairs and connections where pipe sizes change. The insert x insert design eliminates threaded transitions and offers a smooth internal profile to reduce flow restriction. Keep clamps tight and inspect periodically for wear.

Suitable for contractors, landscapers, and homeowners, the fitting is sold individually and stocked for fast fulfillment. Store in a cool, dry place away from direct sunlight to preserve material properties; avoid prolonged exposure to solvents or strong chemicals. For potable systems, follow local codes and installation practices.
