The Tape Loc x 1/4" Barb w/ Valve is a specialized takeoff fitting designed to initiate 5/8" drip tape rows from 1/2" or larger polyethylene mainline using a standard 1/4" punch. By integrating a manual shut-off valve directly into the takeoff barb, this fitting allows you to manage water flow on a row-by-row basis, making it ideal for gardens with diverse crop needs or staggered harvesting schedules.
Utilizing the industry-leading Tape Loc mechanical locking system, this adapter ensures a blowout-proof connection to your drip tape. It is a highly versatile choice among professional irrigation fittings for market farmers and home gardeners who require the convenience of 1/4" micro-fittings combined with the high-uniformity performance of agricultural-grade tape.

Install row-control takeoffs in four easy steps.
Step 1: Punch the Mainline
Lay out your 1/2" (or larger) poly tubing. Use a standard 1/4" Punch Tool like the Purple Handle or Miracle Punch to create a clean hole where you want your drip tape row to start.
Step 2: Insert the Barb
Push the 1/4" barb end of the fitting into the punched hole until it snaps into place. Ensure the valve handle is easily accessible for future adjustments.
Step 3: Prepare the Tape
Rotate the Tape Loc nut backwards (towards the valve) to expose the sharp tape barb. Slide your 5/8" drip tape over the barb until it hits the stop.
Step 4: Lock and Control
Twist the locking nut forward over the tape and hand-tighten firmly. Use the red handle (parallel to the valve for "on", perpendicular for "off") to test and manage your row flow.
