Netafim Techline EZ 12mm Insert Cross

A quick guide to correctly inserting your 12mm cross fitting for a leak-proof grid.

Step 1: Cut the Tubing
Using a pair of tubing cutters, make a clean, straight 90-degree cut on the ends of your 12mm Netafim Techline EZ tubing. Jagged cuts can lead to leaks around the barbs.

Step 2: Warm the Tubing (Optional)
If your tubing feels cold or stiff, let the ends sit in direct sunlight for 10 minutes or briefly dip them in hot water. This softens the plastic, making insertion significantly easier.

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

Step 4: Connect Remaining Branches
Repeat the push-fit process on the remaining three sides of the cross to complete your intersection, ensuring all four tubes are pushed firmly against the center of the fitting.

During spring startup, how do I check the Netafim Techline EZ 12mm Insert Cross for freeze damage?
Turn on the water and inspect the Netafim Techline EZ 12mm Insert Cross for hairline cracks or dripping. If the winter freeze stretched the tubing or cracked the plastic, replace the fitting to prevent blowouts.

Water expanding during winter freezes can sometimes warp the rigid plastic of the fitting or permanently stretch the tubing around the barb. Doing a visual check during spring startup ensures your grid runs perfectly all season.

Can I use the Netafim Techline EZ 12mm Insert Cross with standard 1/2-inch tubing?
No, this cross fitting is designed exclusively for 12mm tubing with a 0.426-inch inside diameter. Standard 1/2-inch tubing is too large and will leak immediately.

Standard 1/2-inch poly tubing typically has an inside diameter of 0.600". If you try to use this 12mm fitting with that tubing, it will slide right off as soon as the system pressurizes.

Does the Netafim Techline EZ 12mm Insert Cross require hose clamps?
No, the Netafim Techline EZ 12mm Insert Cross does not require hose clamps. The sharp barbs create a secure friction fit that holds water effectively up to 50 PSI.

As long as you are using the correct 12mm tubing and your water source is properly pressure-regulated below 50 PSI, the friction from the barbs is all that is necessary for a permanent seal.

How do I remove a Netafim Techline EZ 12mm Insert Cross if I need to change my layout?
Do not try to pull the Netafim Techline EZ 12mm Insert Cross out, as you may damage the barb. Instead, slice the tubing carefully along the barb or cut the tubing entirely and use a fresh section.

Because these fittings are designed to grip tightly, pulling on them can warp the barbs, leading to leaks if you try to reuse them later. Cutting the tubing off is the safest removal method.
