Netafim Techline EZ 12mm Male Adapter 1/2"

A quick guide to correctly installing your threaded insert adapter for a leak-proof seal.

Step 1: Tape the Threads
Wrap the 1/2-inch Male Pipe Thread (MPT) side of the adapter with 2 to 3 layers of thread sealant tape. Never use liquid pipe dope on plastic irrigation fittings.

Step 2: Thread the Fitting
Hand-tighten the taped threaded end into your 1/2-inch Female Pipe Thread (FPT) PVC or manifold fitting. Do not over-tighten with a wrench, as this can crack the plastic.

Step 3: Cut the Tubing
Using a pair of tubing cutters, make a clean, straight 90-degree cut on your 12mm Netafim Techline EZ tubing. Avoid using jagged scissors, which can cause leaks around the barb.

Step 4: Push the Tubing On
Firmly grasp the tubing and push it straight over the barbed end of the adapter. Rock it slightly side to side until the tubing slides completely over the barb and sits flush against the center stop.

During spring startup, how do I check the Netafim 12mm Male Adapter (1/2") for winter damage?
During spring startup, turn on the water and inspect the threaded connection of the Netafim 12mm Male Adapter (1/2") for hairline cracks or dripping. Freezing water can sometimes split rigid plastic threaded connections.

If you notice a leak around the threads, you may simply need to re-apply fresh thread sealant tape. If the plastic body itself is cracked from a winter freeze, the adapter must be replaced.

Will the Netafim 12mm Male Adapter (1/2") fit standard 1/2-inch poly tubing?
No, the barbed end is designed exclusively for 12mm tubing with an inside diameter of 0.426 inches. Standard 1/2-inch poly tubing has a larger 0.600-inch ID and will leak immediately.

Attempting to use this 12mm fitting on standard 1/2" tubing will result in a completely loose fit. Always match your barbed fittings directly to your tubing's inside diameter.

Do I need to use thread sealant tape on the Netafim 12mm Male Adapter (1/2")?
Yes, you should apply two to three wraps of thread sealant tape to the 1/2-inch threaded side of the Netafim 12mm Male Adapter to ensure a watertight seal. Do not use pipe dope.

Thread sealant tape fills the tiny gaps in the plastic threads, preventing weeping and leaks. Apply it clockwise to match the direction you will be turning the fitting.

Does the barbed side of the Netafim 12mm Male Adapter (1/2") require a hose clamp?
No, the barbed side of the Netafim 12mm Male Adapter (1/2") does not require a hose clamp. The sharp barbs create a secure friction fit that withstands pressures up to 50 PSI.

As long as you are using the correct 12mm tubing and keeping your system pressure properly regulated, a hose clamp is unnecessary.
