Managing water flow to individual rows is essential for precision irrigation. The Tape Loc x 1/2" MPT w/ Valve combines a secure tape connector with a manual shut-off valve, allowing you to connect 5/8" drip tape directly to 1/2" PVC risers or manifolds while retaining full control over that specific line.
Perfect for rotating crops, maintenance, or varying water needs, this fitting threads into any standard 1/2" Female Pipe Thread (FPT) fitting. The large, easy-to-turn handle lets you open or close the flow instantly, while the Tape Loc nut ensures your drip tape remains securely attached without leaks.
Understanding compatibility is key to a successful installation. The Tape Loc system is engineered exclusively for flat drip tape, not solid poly tubing.

Step 1: Preparation (Threaded Side)
Wrap the 1/2" MPT threads with Thread Sealant Tape. Screw the fitting into your 1/2" PVC fitting or riser. Hand-tighten plus a quarter turn—do not over-tighten.
Step 2: Prepare Tape
Cut your drip tape squarely with scissors. Critical Tip: Inspect the cut end. If there is a hard plastic emitter inside the tape within the first inch, cut it off. Trying to lock the fitting over an emitter is the most common cause of leaks!
Step 3: Unlock
Rotate the locking nut counter-clockwise (backwards) towards the center of the fitting body. This exposes the sharp barb. Do not remove the nut completely.
Step 4: Insert
Slide the drip tape over the barb. Push it until it hits the plastic stop on the body of the fitting. It should go past the raised ridge on the barb.
Step 5: Lock
Twist the locking nut clockwise (outward) so it travels over the tape. Tighten firmly by hand. The nut compresses the tape against the barb, creating a permanent seal.
Troubleshooting: If a leak appears on the tape side, do not use pliers. Back the nut off, check that the tape is fully seated and not folded, and retighten by hand.
This fitting is for 5/8" Drip Tape ONLY.
