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. |
