The Barbed Female Pipe End (also known as a Female Adapter) is a versatile insert fitting designed to bridge the gap between rigid threaded components and flexible irrigation lines. Whether you are connecting to a PVC riser, a filter outlet, or a manifold, this adapter provides a secure point to attach your Polyethylene Tubing directly to the system.
Molded from durable Schedule 40 PVC, these fittings feature a Female Pipe Thread (FPT) on one side and a multi-ridged Insert Barb on the other. This robust construction ensures that once clamped, the tubing stays firmly in place, managing high flow rates and pressure fluctuations common in agricultural and commercial landscape applications.
Key details for system planning and compatibility.

Follow these steps to create a leak-free threaded-to-barb connection.
Step 1: Seal the Threads
Apply thread seal tape to the Male threads of the riser or fitting you are connecting to. Wrap clockwise 3-5 times.
Step 2: Thread the Adapter
Screw the Barbed Female Adapter onto the taped male threads. Hand-tighten firmly, then give it an extra turn with a wrench if necessary. Do not overtighten as PVC can crack.
Step 3: Prep the Tubing
Slide a stainless steel hose clamp onto your poly tubing. If the tubing is stiff, dip the end in hot water to soften it.
Step 4: Insert and Clamp
Push the tubing onto the barbed end of the adapter until it completely covers the barbs. Slide the clamp into position (over the barbs) and tighten with a nut driver.
