The Tape Loc x 1/2" MPT w/ Valve is the engineered solution for connecting drip tape rows to threaded manifolds or risers with individual flow control. By integrating a high-quality manual shut-off valve into a 1/2" Male Pipe Thread (MPT) adapter, this fitting allows you to isolate specific beds or rows without affecting the rest of your system. It is designed to thread directly into standard PVC Tees or elbows, creating a compact and modular row-start assembly.
Managing diverse crop rotations or varying water requirements is simplified with a quarter-turn handle that provides instant "on/off" capability at the source. This is one of our most popular irrigation fittings for greenhouse manifolds, raised bed headers, and high-tunnel systems where row-by-row control is essential for maximizing water efficiency and crop yield.
Ensure proper system compatibility and pressure management.

Install row-control valves in minutes.
Step 1: Prep the Threads
Apply 3-4 wraps of thread seal tape to the 1/2" MPT end of the valve. Screw it into your PVC tee or manifold port. Hand-tighten plus a quarter turn—do not overtighten.
Step 2: Prepare the Tape
Rotate the Tape Loc nut counter-clockwise (backwards) to expose the sharp tape barb. Ensure your 5/8" drip tape is cut squarely.
Step 3: Insert and Seat
Slide the drip tape over the barb until it hits the plastic stop. Ensure the tape is straight and not bunched at the base.
Step 4: Lock it Down
Twist the locking nut clockwise (forward) over the tape. Tighten firmly by hand to compress the tape against the barb.
Step 5: Control Flow
Turn the red handle 90 degrees to shut off the water, or parallel to the fitting to open it. Turn on your water source and check for leaks.
