Durable PVC insert reducing coupling engineered to transition 2" polyethylene tubing down to 1" tubing with secure barbed insert-to-insert connections. The gray PVC construction resists abrasion and common environmental exposure, making it suitable for irrigation, drip-line, pond, and general poly-pipe applications.

  • Material & finish: Schedule 40 PVC in gray for corrosion resistance and reliable service life.
  • Sizes: 2" (large) to 1" (reduced) barbed ends — designed for standard polyethylene tubing and flexible poly hose.
  • Connection type: Insert x insert (barbed) for a simple push-fit assembly; tubing should be pushed fully onto all barbs to reach the center stop.
  • Installation: Slide appropriately sized hose clamps onto the tubing before insertion, then tighten clamps on both ends to ensure a leak-resistant joint.
  • Applications & benefits: Ideal for irrigation systems, drip networks, and quick repairs — provides a compact, low-profile transition without threaded adapters.

Compatible with common poly tubing and flexible hoses; to ease insertion on larger sizes, warm the tubing or soak the end in hot water briefly and then push onto the barbs. Verify tubing inner diameters and use clamps rated for outdoor conditions.

Sold individually with the manufacturer's part number 1429-249. For best results, use with compatible poly tubing and stainless-steel or galvanized hose clamps; periodically inspect clamp tightness. This fitting is intended for non-pressurized or low-pressure irrigation use—consult product documentation or the manufacturer for pressure ratings and potable water suitability.
