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.

High-Temperature Heat-Shrink Tubing
Use this tubing in applications where temperatures reach up to 500° F. It’s often used to insulate electronic components. Tubing resists abrasion and chemicals. Semi-rigid, it bends only slightly.
PTFE tubing is more chemical resistant than PEEK.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown. The higher the dielectric strength of a material, the better it is for preventing electricity, heat, or signal from dissipating from wire and cable.

Thin-Wall High-Temperature Heat-Shrink Tubing
- Material: PTFE Plastic
- Shrink Ratio: 2:1
- Dielectric Strength: 455 V/mil
- Shrink Temperature: 655° F
- Temperature Range: -325° to 500° F
With thin walls, this tubing shrinks faster than other high-temperature tubing. Made of PTFE, it withstands temperatures up to 500° F and resists abrasion and chemicals. It’s also UV resistant, so it won’t fade in sunlight.
Tubing with a 0.006" – 0.01" minimum wall thickness after shrinking is often used on extremely thin (0.014" - 0.038") guide wire to help maintain the thinness of the wire. It’s also good for splicing fiber optics—it minimizes damage to the fibers.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.

Harsh Environment Heat-Shrink Tubing Assortments
Maintain a supply of tubing in a variety of sizes and materials that withstands harsh conditions such as abrasion, moisture, and chemicals.
PVC tubing has excellent resistance to chemicals, oil, and acids.
Polyolefin is for general purpose use. Polyolefin with adhesive creates a water-resistant seal; the adhesive melts when heated and bonds to the underlying surface.
PTFE has excellent abrasion resistance and withstands higher temperatures than other tubing.
FEP tubing is high strength to resist abrasion, cuts, tears, and chemicals.
PVDF resists abrasion, cuts, and tears.
