Replacing a Valken V12 Macro Line
A damaged or leaking Valken V12 macro line should be replaced only with tubing that matches the system’s documented size, material and pressure requirements. Do not choose tubing by appearance alone.
Before opening the system
- Remove the air source and fully degas the system.
- Confirm there is no stored pressure.
- Record the original routing and insertion depth.
- Check the manufacturer’s documentation for the correct tube and fitting specification.
Replace the line carefully
Release the fitting collar with the correct method and withdraw the old tube without twisting the fitting body. Cut the replacement square with an appropriate tube cutter. The end must be clean and free of deformation. Insert it to the documented depth and route it without kinks, sharp bends or contact with moving parts.
Leak-check before use
Pressurize the system gradually using the maker’s specified procedure. Check each connection with an approved leak-detection method. If a fitting leaks, degas the system again before reseating or replacing the tube. Never tighten or cut a pressurized line.
