The Dura Plastics Barbed Male Pipe End (Male Adapter) is the professional choice for transitioning from flexible polyethylene tubing to rigid PVC components. Whether you are connecting a mainline to a ball valve, filter, or pressure regulator, this fitting ensures a reliable link. Molded from heavy-duty Schedule 40 PVC, these adapters feature sharp barbs for a tenacious grip on your tubing and precision-molded threads for a secure, leak-free connection.
They are essential irrigation fittings for integrating poly tubing with any Female Pipe Thread (FPT) component, though they must be secured with hose clamps to handle system pressure.

Follow these steps to ensure a secure connection.
Step 1: Prepare Threads
Wrap Thread Sealant Tape around the Male Pipe Threads (MPT) to ensure a watertight seal. Screw the fitting into your female threaded component (valve, filter, etc.) and hand-tighten.
Step 2: Prepare Tubing
Cut your poly tubing squarely. Pro Tip: Dip the end of the tubing in warm water or let it sit in the sun to soften it. This makes inserting the barb significantly easier.
Step 3: Insert Fitting
Push the poly tubing over the barbed end of the adapter. Use a rocking motion and ensure the tubing goes over all the barbs for maximum hold.
Step 4: Secure with Clamp
Slide a Stainless Steel Hose Clamp over the tubing where it overlaps the barbs. Tighten the clamp with a nut driver or screwdriver to prevent blowouts under pressure.
