Green-Handle Barb to Male Thread Drip Irrigation Valve

Start a lateral from a threaded supply

A male-thread connection and stepped barbed outlet combine branch connection and manual shut-off. The green handle lets you close the attached lateral for maintenance.

Match both ends separately

Listed combinations use 16, 20 or 25 mm barbs with selected 1/2-inch or 3/4-inch threads. Check the exact pairing and receiving thread standard. Fit tubing fully, seal the threaded joint appropriately and leave room for handle movement.

Choose a transition that stays accessible

The stepped barb and male-thread end perform different connection jobs. The barb holds compatible flexible tubing while the thread screws into a receiving fitting. Select the combination from the labelled options instead of choosing by the valve handle color. Position the threaded transition where the tubing can leave in a straight, supported direction rather than pulling sideways on the body.

Inspect before the watering season

Turn the handle with the branch depressurized and check that both positions remain accessible. Examine tubing around the barb for splits or permanent distortion, then inspect the threaded joint as the system fills. A leaking connection needs a fit or sealing check; forcing the handle will not correct it. Close and isolate the supply before removing the valve, and flush accumulated debris before reconnecting the branch.
