Sheathing Materials and Information
Adding a resin/rubber coating to a flexible tube provides the following additional benefits:
– Waterproof/resistant
– Oil-proof/resistant
– Attractive appearance
– Additional strength
– Superior insulation
**The following chart displays the most common materials available. Please consult us regarding specifications, minimum lot, delivery date, sheathing combinations, and additional materials available (including any heat or chemical resistance requirements).

PVC Sheathing Varieties
| Figure Num. | Sheathing Variety | Part Number Code | Features |
| 1 | Tight-Fitting | KSP- __N | – Standard item – PVC fills the spiral valley to make the finished surface even and smooth. |
| 2 | Vacuum Sheathing | KSP-__N-B | – During processing, sheathing is applied in a vacuum. – The finished surface maintains the spiral pattern of the coil. |
| 3 | Bagging Sheathing | KSP-__N-F | – Sheathing is applied only on the surface of the tube and the spiral valley contains no PVC. The surface of the sheathing will be completely smooth. |
| N/A | Heat Shrink Sheathing | KSP-__N + Shrink tube type# | – Please contact us for more details. |
Other Services
Double Washing and Chemical Polishing
Double washing:
Double washing treatment (using detergent) can be applied to tubes for high precision applications.
Chemical polishing:
We offer tubes with chemical polishing, providing extra shine for optical applications.
※ Special polishing for semiconductor-quality applications also available.
How to Measure the Bend Radius
- Hold both ends of the tube at the tips, so that the tube is in a hanging state. (The tube should be about at least 50 cm in length.)
- Crisscross the ends over each other to make a loop, until you feel a very slight resistance.
- Lay it on a flat surface and slowly pull the ends.
- When the coiled tube is pulled the top part will lift.
- Measure the radius in this state.
- This will result in the measurement of the natural bend radius. **Note that you will be able to force the tube to a smaller bend radius; however it would not be the natural bend radius, which is the basis of our tubing.
View the figure below.
How to Measure the Bend Radius – Shafts
- Bend the tube until the point where it stops.
- Measure the radius in this state.
- This will result in the measurement of the natural bend radius.
