Junkosha Flat and Coil Tubing

Flat Tubing

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.
