The 1/2" Easy Loc x .400 Barb w/ Shutoff Valve is a professional-grade "takeoff" fitting designed to connect a 1/2" drip line directly to a larger supply header. Instead of cutting your heavy-duty tubing to install a tee, this valve allows you to punch a hole and insert a branch line anywhere you need it. It is an essential component for zoning vegetable gardens or row crops, giving you the ability to turn off individual rows when they don't need water—perfect for managing crop rotation alongside your timers and controllers.
This fitting features a specialized .400 barb on the inlet side, which is designed to handle higher flow rates than standard 1/4" connectors. It snaps securely into 3/4" or larger poly tubing (or PVC with a grommet), while the outlet side uses reliable Easy Loc technology to grip standard 1/2" irrigation fittings and tubing. The oversized handle provides smooth, 90-degree on/off operation, ensuring you have total control over your system's water distribution.
Ensure you have the correct tubing sizes for this connection.

Install a valved branch line in seconds.
Step 1: Punch the Header
Using the required .400 Barb Punch, create a hole in your 3/4" (or larger) mainline tubing. Note: A standard 1/4" punch is too small.
Step 2: Insert the Valve
Push the barbed inlet of the valve firmly into the punched hole. Listen for a "snap" to ensure the barb has seated fully inside the tubing wall.
Step 3: Connect Branch Tubing
Rotate the Easy Loc locking collar backwards to expose the outlet barb. Push your 1/2" poly tubing onto the barb until it hits the stop.
Step 4: Lock it Down
Twist the locking collar forward (over the tubing) to secure the connection. Hand-tighten only.
