Blue-Handle Male-Thread to Barb Valve for Drip Irrigation

Control a drip irrigation branch at its threaded connection with this compact manual valve. One end screws into a compatible female-thread fitting; the other end pushes into matching polyethylene tubing. The blue handle gives you an accessible shutoff point when you need to isolate a row for inspection, flushing or changes to the layout.

A connection you can check from both sides

The angled view shows the two different ends of a 16 mm barb by 1/2 in male-thread example. Select your size from the purchase options, then check both the thread standard and the tubing's actual inside diameter before installation. A nominal tubing size alone does not guarantee a tight fit.

Fit it to your irrigation branch

• Choose the listed combination of 16 mm or 20 mm barb and 1/2 in or 3/4 in male thread.
• Use a compatible female-thread connection and the appropriate sealing method for that thread type; avoid overtightening the plastic body.
• Cut the tubing square, seat it fully over the barbs and support the line so it does not pull on the valve.
• Flush the branch, open the valve and inspect both joints for leaks at operating pressure.

Sold as one manual valve. Tubing, threaded adapters and installation tools are separate.
