Junkosha’s coil tubing is used as piping for movable parts in many industrial products, including pneumatic equipment, centralized lubrication equipment, dentistry equipment, and industrial robotics. In addition, it enables previously-separated pneumatic and electric circuits to be integrated on a single line.


- Flat polyurethane tubing perfect for centralized piping in rolling flex.
- Mechanically strong, with particularly superior abrasion resistance.
- Flexible and highly resilient to impacts.
- Combines polyurethane tubing for pneumatic pressure and noise-reducing shielded wire in one unit.
- Air and electric signal circuits can be included on a single line. Flattening provides plenty of flexibility and ease of sliding.
- The built-in shielded cables provide superior bendability using the technology acquired in developing special computer wires.
- The textured tube surface lowers friction, making this product excellent for high-density (space saving) piping work.
- Reduced abrasion and noise from movement.
