Twisted Choppers Aluminum Hard Oil Line Kit for Custom Motorcycles
Hard oil lines give a custom build a clean, mechanical look. This kit is for the builder who wants to make those lines by hand: The tubing is cut to length, bent to shape and joined at each port, one line at a time, so the oil plumbing follows the path you lay out and looks as deliberate as the rest of the bike.
Key Features
- Tubing bender and close-quarters tubing cutter are included, so the tubing is cut and bent without buying either tool separately
- Vibra-Lok fittings seal with a rubber band around the tube, so no flaring is required
- Fittings are made for high-vibration use, where metal-on-metal compression fittings commonly leak
