The Tape Loc Coupler is the industry-standard fitting for joining two lengths of 5/8" drip tape or repairing a damaged section of line. Whether you've accidentally cut your tape with a shovel or need to extend your vegetable rows for the new season, this coupler provides a permanent, leak-proof connection that is significantly more reliable than standard friction-fit barbs.
By utilizing a specialized mechanical locking mechanism, this coupler ensures a blowout-proof seal even as water temperatures fluctuate and the tape softens. It is a fundamental component among professional irrigation fittings for market gardens, vineyards, and commercial row crop operations where system integrity is paramount to crop health.

Repair or extend your lines in four easy steps.
Step 1: Prep the Tape
Ensure the ends of your drip tape are cut squarely with scissors. If repairing a tear, cut out the damaged section completely. Tip: If there is a hard plastic emitter inside the tape within the first inch of the cut, trim the tape back past it.
Step 2: Prepare the Fitting
Rotate both locking nuts backwards (towards the center of the coupler) to expose the sharp tape barbs.
Step 3: Insert and Lock
Slide the first piece of tape over the barb until it hits the center shoulder. Twist the locking nut forward (away from the center) until hand-tight. Repeat the process for the second piece of tape on the opposite side.
Step 4: Test
Turn on your water source and verify the connection is leak-free. Hand-tighten the nuts further if any weeping occurs.
