Description

Repair or Extend Your Poly Tubing. Secure & Durable.

The Dura Plastics Barbed Coupler is the simplest and most cost-effective solution for joining two pieces of polyethylene tubing. Whether you are repairing an accidental cut in your mainline or extending a zone to reach new plants, this insert fitting ensures a reliable, unrestricted connection. Molded from heavy-duty Schedule 40 PVC, these couplers feature sharp barbs on both ends for a tenacious grip on your tubing. They are an essential "emergency kit" item for any professional landscaper or home gardener.

These irrigation fittings are designed to withstand the elements and provide a long-lasting seal when secured with hose clamps (required for pressures over 20 PSI).

Why Choose Dura Barbed Fittings?
  • Instant Repairs: Quickly fix damaged tubing by cutting out the bad section and inserting a coupler to restore flow.
  • Heavy-Duty Construction: Made in the USA from high-quality Schedule 40 PVC, ensuring superior resistance to UV rays, chemicals, and impact.
  • Secure Grip: The multi-barb design provides a tight, friction-based seal that resists pull-out.
  • Cost-Effective: The most affordable way to extend a drip line or repair a leak permanently.
  • Wide Range of Sizes: Available in sizes from 1/2" to 2" to match your specific mainline requirements.

How to Install: A Step-by-Step Guide

Follow these steps to ensure a leak-proof connection.

Step 1: Cut Tubing
Cut your mainline poly tubing at the point of repair or extension. Ensure the cut is square and clean.

Step 2: Prepare Tubing
Pro Tip: Soften the ends of the poly tubing by dipping them in warm water or letting them sit in the sun. This makes inserting the barbs significantly easier.

Step 3: Insert Fitting
Push the poly tubing onto each barbed end of the coupler. Use a rocking motion and ensure the tubing goes over all the barbs to the stop for maximum hold.

Step 4: Secure with Clamps
Slide a Stainless Steel Hose Clamp over each connection point where the tubing overlaps the barbs. Tighten firmly with a nut driver to prevent blowouts under pressure.

✔ Compatibility Check

Check your tubing sizes:

  • Both Ends: Fit INSIDE standard Poly Tubing (Match ID sizes).
  • This fitting connects Tubing to Tubing.
  • Pressure Warning: Barbed fittings REQUIRE hose clamps for pressures over 20 PSI to prevent leaks or disconnection.
  • It will NOT fit flat Drip Tape or PVC Pipe (use correct adapters for those).

Complete Your System

Ensure your installation is secure and professional with these essentials:

  • Stainless Steel Hose Clamps: Essential for securing the tubing to the barb to prevent leaks or blowouts.
  • Poly Tubing: The flexible mainline that pairs with these barbed couplers.
  • Hold Downs: Secure your tubing in place to prevent movement or strain on connections.
  • Tubing Cutter: Ensure clean, square cuts for the tightest possible seal.
