About Heat-Shrink Tubing

High-Temperature Moisture-Seal Heat-Shrink Tubing

- Material: PTFE Plastic
- Shrink Ratio: See Table
- Dielectric Strength: 455 V/mil
- Shrink Temperature: 660° F
- Temperature Range: -450° to 450° F
Create a moisture-resistant seal in applications where temperatures reach up to 450° F. The inner lining melts when the tubing is heated and bonds to the underlying surface, creating a water-resistant seal. Made of PTFE, it also resists abrasion and chemicals. Choose tubing with a larger shrink ratio to create a tight seal over irregularly shaped objects.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.
