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.
