Heavy-Duty 17mm Blank Tubing for Custom Drip Systems
The Netafim Techline Copper CVXR Blank Tubing (250′ Roll) is a professional-grade, highly durable water delivery line designed for fully customized drip irrigation setups. Unlike standard emitter tubing, this “blank” line contains no pre-installed drippers. It allows you to build a robust solid mainline to transfer water efficiently to remote garden zones, or act as a blank canvas where you can manually punch in your own external drip emitters exactly where your individual plants are located. Because it connects seamlessly with professional 17mm barbed fittings, it is an incredibly adaptable addition to any small, medium, or complex landscape design.
Engineered with the legendary reliability of the Netafim Techline series, this 17mm tubing (0.66″ OD / 0.56″ ID) is color-matched to easily blend with your existing Techline CVXR emitter tubing installations. It is highly UV-resistant and built to thrive in both on-surface and sub-surface applications. Its flexible polyethylene construction allows for an exceptionally tight 7-inch bending radius, meaning it can easily weave through densely packed flower beds, wrap around tree bases, and navigate angular planters without kinking.
- Completely Customizable: Features no pre-installed emitters, giving you the absolute freedom to space your own punch-in emitters precisely where each plant needs water.
- Incredible Flexibility: The soft yet durable construction boasts a 7-inch bending radius to easily navigate sharp corners and complex landscape layouts.
- Sub-Surface Ready: Built from heavy-duty, UV-resistant materials that can confidently be left on the surface or buried underground for invisible irrigation.
- Leak-Proof 17mm Sizing: Manufactured to strict 17mm standards, ensuring a perfectly tight, blowout-resistant seal when used with dedicated 17mm insert fittings.
- Versatile Application: Perfect for acting as a supply header to feed smaller 1/4″ micro-tubing lines, or as a solid transfer line between distant garden beds.

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.
