Sheathing Materials and Information

Processing the flexible tube with a resin/rubber coating provides the following additional benefits:

  • Waterproof/resistant
  • Oil-proof/resistant
  • Attractive appearance
  • Additional strength
  • Superior insulation


The following chart displays only some of the materials available. Please consult us regarding specifications, minimum lot, delivery date and materials available (including any heat or chemical resistance requirements).

Ordering Instructions:

  • Add material code after alphabetical model

PVC Sheathing Varieties:

There are four types of PVC sheathing available for Square-Lock Type A (Casing) Tubes:

PVC Sheathing Varieties

Tight-fitting KSP-__N Standard item. PVC fills the spiral valley to make the finished surface even and smooth. fig. 1
Vacuum Sheathing KSP-__N-B During processing, sheathing is applied in a vacuum. The finished surface maintains the spiral pattern of the coil. fig. 2
Bagging Sheathing KSP-__N-F Sheathing is applied only on the surface of the tube and the spiral valley contains no PVC, however the surface will be completely smooth. fig. 3
Heat Shrink Sheathing KSP-__N Please contact us for details  

 

Other Services

Standard vs. 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.

Assembly:

We can de-burr the casings/tubing and affix the necessary connectors or fittings to the assembly for your project. Please see our Assembled Products Page.

Optical Fiber Insertion:

Using special techniques, cables or optical fibers can be inserted into up to 1000 meters of flexible tube and placed on a reel.

Spooling:

We can deliver flexible tubes on plastic reels for easy handling and maintenance.
