Green-Handle Inline Barb Shut-Off Valve for Drip Tubing

Add isolation inside a drip lateral

Barbed connections at both ends join two sections of compatible tubing. The green handle provides a visible manual shut-off point for a branch or section of a planted row.

Select the tubing fit

Choose 16, 20 or 25 mm and compare tubing inner diameter and wall thickness with the selected barb. Cut tubing squarely, insert both ends fully and support the joint. Inspect for leaks at operating pressure before servicing downstream outlets.

Place shut-off control where it helps

This inline valve has a stepped barb on each side and a broad green handle above the body. Use it at a point that remains easy to reach as plants grow, such as the start of a branch or a service boundary in a lateral. Choose each installed valve for the tubing used at that location; the different listed sizes are separate connection options.

Keep the branch supported during service

Allow enough straight tubing beside both ends to avoid bending the connection sharply. Operate the handle gently when testing the branch and confirm downstream watering resumes after reopening. Before seasonal use, inspect tubing for cracking or stretching around the barbs and check the valve body for damage. Isolate and depressurize the supply before disconnecting either end. Flush debris from the lateral before returning the serviced section to normal watering.
