2" x 1-1/4" insert reducing coupling (1429-250) — a durable PVC/poly fitting engineered to join two different sizes of flexible poly tubing in irrigation and low-pressure water systems. The barbed insert x insert design provides a secure, leak-resistant connection when used with appropriate clamps.

  • Material: Rigid PVC/poly material formulated for hose and poly tubing applications.
  • Sizes: Connects a 2" tube to a 1-1/4" tube (nominal sizes).
  • Connection: Barbed insert x insert ends for slip-in installation on flexible tubing.
  • Standards: Manufactured to ASTM D2609 material specifications and compatible with common irrigation standards.
  • Potable water: Listed/marketed as NSF-compatible in distributor spec listings for potable water use.
  • Temperature & durability: Rated for typical irrigation temperatures (up to ~140°F) and resists corrosion and many chemicals.
  • Installation: Use stainless-steel worm-gear or cinch clamps on both barbs for a secure seal.

This reducing coupling is ideal for joining polyethylene or other flexible tubing in irrigation, sprinkler, and general-purpose fluid-transfer applications. It is commonly used where a straight-line reduction is required between two hose sizes; install with compatible clamps and test system pressure after assembly.
