Netafim Techline EZ 12mm Insert Elbow

A quick guide to correctly inserting your 12mm fittings for a leak-proof seal.

Step 1: 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.

Step 2: Warm the Tubing (Optional)
If the tubing is cold and stiff, let the ends sit in direct sunlight for 10-15 minutes, or dip the tip briefly in hot water to soften the plastic and make insertion easier.

Step 3: Push the Fitting In
Firmly grasp the tubing and push the Netafim Techline EZ 12mm Insert Elbow straight into the open end. Rock the fitting slightly side to side as you push until the tubing slides completely over the barb and sits flush against the center stop.

Step 4: Connect the Other Side
Repeat the process on the other side of the elbow to complete your 90-degree turn.

Will the Netafim Techline EZ 12mm Insert Elbow fit standard 1/2-inch mainline tubing?
No, this elbow will not fit standard 1/2-inch mainline tubing. It is designed specifically for 12mm tubing with an inside diameter of 0.426 inches, making it significantly smaller than standard 1/2-inch poly.

Attempting to use this fitting on standard 1/2" tubing (which typically has a 0.600" ID) will result in a completely loose fit and immediate leaks. Always match your fittings to your tubing's inside diameter.

Does the Netafim Techline EZ 12mm Insert Elbow require a hose clamp to prevent leaks?
No, hose clamps are not required. The sharp barbs on the Netafim Techline EZ 12mm Insert Elbow create a secure grip inside the tubing that holds water effectively up to 50 PSI.

As long as your system has a proper pressure regulator installed at the water source keeping the pressure below 50 PSI, the friction from the barb is all you need for a permanent seal.

How do I fix a leaking Netafim Techline EZ 12mm Insert Elbow when checking my system this spring?
To fix a leaking connection during spring startup, cut off the stretched end of the tubing entirely, then firmly push the Netafim Techline EZ 12mm Insert Elbow into a fresh section of the pipe.

Winter freezing and thawing can sometimes stretch the tubing around the barb. Simply pushing the fitting deeper rarely works; making a fresh cut is the most reliable way to restore a watertight seal for the new season.

What is the best way to push the Netafim Techline EZ 12mm Insert Elbow into stiff tubing?
The best way to push the Netafim Techline EZ 12mm Insert Elbow into stiff tubing is to leave the tubing in direct sunlight for 15 minutes or briefly dip the end in warm water to soften the plastic.

Never use grease, soap, or oil to lubricate the fitting, as these materials can degrade the plastic or cause the fitting to slip out under pressure later on. Heat is the only necessary tool.
