Jan 22nd 2026
The Tape Loc x .400 Barb is the industry-standard takeoff fitting for initiating drip tape rows from a polyethylene distribution line. Designed specifically for use with a .400 punch tool, this adapter provides a streamlined transition from your poly mainline directly to 5/8" drip tape.
By utilizing a positive-locking mechanism, this fitting eliminates the need for clamps or glue, ensuring your rows stay connected even in the demanding conditions of commercial vegetable farming. It is a fundamental component among professional irrigation fittings for row crop systems, market gardens, and small acreage plots where high-uniformity irrigation is required.

Follow these steps to start your drip tape rows.
Step 1: Punch the Mainline
Lay out your 3/4" (or larger) poly tubing. Use .400 Barb Punch Tool (SKU: PU400NEW) to create a specifically sized hole. Note: Standard 1/4" punches are too small for this fitting.
Step 2: Insert the Adapter
Push the small .400 barb end of the fitting into the punched hole. You should feel a distinct "snap" as the barb seats against the internal wall of the tubing.
Step 3: Prepare the Tape
Rotate the locking nut counter-clockwise (backwards) to expose the sharp tape barb. Slide your 5/8" drip tape over the barb until it hits the plastic shoulder.
Step 4: Lock it Down
Twist the locking nut clockwise (forward) over the tape. Hand-tighten firmly to compress the tape and create a watertight seal.
Verify your punch and tubing size:
