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.
Check your tubing sizes:
