The 1/2" Easy Loc x .400 Barb Adapter is a specialized start connector designed to branch a 1/2" drip line off of a larger supply header. It features a standard Easy Loc connection for 1/2" Mainline Tubing (.700" OD) on one side and a large .400" barb on the other, designed to insert directly into a hole punched in your supply pipe. This fitting is the perfect solution for creating a secure takeoff point using a .400 Barb Punch.
This fitting is essential for custom manifold builds where you need to run multiple 1/2" distribution lines from a single large-diameter pipe. As part of our professional line of irrigation fittings, it combines the reusability of Easy Loc with a high-flow barbed intake, ensuring you can expand your system efficiently.
Verify your hole size requirements.

Create a secure branch from your main supply line.
Step 1: Punch the Supply Line
Use a .400 Barb Punch to create a clean hole in your larger supply header (such as 3/4" or larger poly tubing, or Layflat).
Step 2: Insert the Barb
Push the barbed end of the adapter firmly into the punched hole. Ensure the barb shoulder sits flush against the supply tubing wall. (Tip: Insert while the tubing is warm).
Step 3: Connect 1/2" Tubing
Rotate the Easy Loc locking collar backwards to expose the barb. Push your 1/2" poly tubing onto the fitting. Twist the collar forward to lock it down.
