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.
