The 1 1/2" Dura Barbed Elbow is a heavy-duty insert fitting designed for large-scale agricultural and commercial irrigation systems. It allows you to make a sharp 90-degree turn in your 1 1/2" Poly Mainline Tubing (oval hose) without crimping or kinking the hose, ensuring consistent water delivery to your crops.
Manufactured from high-impact grey PVC, this fitting features sharp, multi-barb ridges that grip the inside of the tubing securely. When used with stainless steel worm gear clamps, it creates a permanent, high-pressure connection ideal for feeding large zones, greenhouses, or orchards.
Reliable specifications for commercial-grade installations.

Installing large insert fittings requires leverage and clamps. Follow these steps for a secure fit.
Step 1: Prep the Tubing
Cut your 1 1/2" poly tubing squarely. Tip: For larger tubing, softening the end with hot water or leaving it in the sun for a few minutes makes installation significantly easier.
Step 2: Position the Clamps
Slide a stainless steel worm gear clamp onto each section of tubing before inserting the fitting.
Step 3: Insert the Elbow
Push the barbed ends of the elbow securely into the tubing until the tubing completely covers all barbs and sits flush against the fitting body. A rocking motion helps.
Step 4: Secure the Clamps
Slide the clamps up so they are positioned over the barbs (but not at the very edge). Tighten firmly using a nut driver or flathead screwdriver to ensure a leak-proof seal.
Ensure you have the right size tubing:
