The Dura 1 1/2" Barbed Elbow is a robust insert fitting designed to create a secure 90-degree turn in large-diameter polyethylene tubing. Built for high-volume agricultural and commercial systems, this elbow allows you to route your 1 1/2" mainline around corners or obstacles without kinking the pipe. Because this fitting handles significant water volume, it must be secured with hose clamps to prevent blowouts under pressure.
Reliable and cost-effective, Dura insert fittings are essential irrigation fittings for growers who need to move large amounts of water efficiently through oval hose or standard poly tubing.
Specifics for large-diameter system planning.

Large fittings require heat and clamps for a proper seal.
Step 1: Cut & Prep
Cut your 1 1/2" poly tubing squarely. Slide clamp onto the tubing BEFORE inserting the fitting.
Step 2: Heat the Tubing
Large diameter poly tubing is stiff. Use hot water or a heat gun (carefully) to soften the end of the tubing. This makes insertion much easier.
Step 3: Insert Fitting
Push the barbed end of the elbow into the tubing. Rocking it back and forth helps. Ensure the tubing covers all the barbs.
Step 4: Clamp It
Slide the clamp up over the barbed area (but not over the retaining ridges at the end). Tighten firmly with a nut driver.
Verify your tubing size:
