Connecting low-pressure drip tape to a water source often involves navigating complex manifolds or risers. The Tape Loc x 1/2" MPT Adapter is the professional choice for threading 5/8" drip tape directly into female pipe thread (FPT) fittings, regulators, or PVC risers.
Whether you are building a custom head assembly or converting an existing 1/2" sprinkler riser to a drip irrigation zone, this fitting provides a secure, leak-proof transition. The male pipe threads allow for easy integration with standard irrigation components, while the Tape Loc nut ensures your tape stays put, even under pressure.
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.
A leak-free connection is only one part of the equation. Ensure your drip tape system lasts for years by pairing this adapter with:
