The Dura Plastics Barbed Plug is the reliable, professional solution for permanently closing off the end of a polyethylene tubing run. Whether you are finishing a new zone or capping off a line that is no longer in use, this insert fitting ensures a leak-proof termination.
Molded from heavy-duty Schedule 40 PVC, these plugs feature sharp barbs that create a tenacious grip inside the tubing. Unlike temporary end closures, this barbed plug is designed for permanent, secure applications where accidental opening is not an option.
Understanding compatibility is key. This fitting plugs the end of poly tubing.

Follow these steps to ensure a secure termination.
Step 1: Cut Tubing
Cut the end of your poly tubing squarely where you want the line to terminate. Ensure the cut is clean.
Step 2: Prepare Tubing
Pro Tip: Soften the end of the poly tubing by dipping it in warm water or letting it sit in the sun. This makes inserting the barb significantly easier.
Step 3: Insert Plug
Push the barbed plug into the open end of the poly tubing. Use a rocking motion and ensure the tubing goes over all the barbs to the stop for maximum hold.
Step 4: Secure with Clamp
Slide a hose clamp over the tubing where it overlaps the barbs. Tighten firmly with a nut driver to prevent blowouts under pressure.
