Netafim Techline CV Blank Tubing 17mm

Install your 17mm blank tubing correctly for optimal performance.

Step 1: Connect to Head Assembly
Connect the blank tubing to your water source using a 17mm adapter. Ensure your system includes a 120-mesh filter and a pressure regulator to prevent blowouts and clogs.

Step 2: Route and Secure
Lay the flexible tubing through your garden beds or trench it slightly below the surface. Use U-shaped hold downs every 3 to 5 feet to keep the line securely pinned in place.

Step 3: Branch or Punch Emitters
Use specialized 17mm barbed fittings to create tees and elbows. If watering plants directly off this line, use an irrigation punch tool to create holes and press your external button emitters into the sidewall.

Step 4: Flush and Cap
Before sealing the system, turn the water on to flush any dirt out of the open line. Once the water runs clear, terminate the end using a 17mm figure-eight line end or end plug.

Does this tubing have watering holes in it?
No, this is "blank" distribution tubing. It has a solid wall with no pre-installed emitters or holes.

It is designed to act as a solid transfer line to move water from your faucet to your garden bed, or as a base line where you can manually punch in individual emitters precisely where you want them.

Can I use standard 1/2" Easy Loc or compression fittings with this?
No, you must use standard 17mm barbed fittings. Standard 1/2" compression or Easy Loc fittings (which are sized for 0.700" OD tubing) are too large and will not create a watertight seal on this 17mm (0.66" OD) pipe.

Attempting to use 0.700" OD fittings will result in leaks and blowouts when the system pressurizes.

Can this tubing be buried underground?
Yes! The Netafim Techline series is highly durable and engineered for both surface and sub-surface applications.

Burying the solid line a few inches underground protects it from lawnmowers and foot traffic while transferring water invisibly across your yard.

How should I prepare my Netafim tubing for spring?
As you prepare for spring watering, it is crucial to open the flush valves or figure-eight ends of your Netafim lines and turn the system on to thoroughly flush out any fine silt, insects, or sediment that accumulated over the winter.

Flushing the blank line before plugging in new emitters or attaching micro-tubing ensures your tiny drip components won't immediately clog on the first watering cycle.
