High-Shrink-Ratio High-Temperature Heat-Shrink Tubing
- Material: PTFE Plastic
- Shrink Ratio: 4:1
- Dielectric Strength: 455 V/mil
- Shrink Temperature: 660° F
- Temperature Range: -325° to 500° F
This tubing shrinks down to a quarter of its original ID, so it creates a tight seal over irregularly shaped objects. Made of PTFE, it withstands temperatures up to 500° F and resists abrasion and chemicals.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.

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.

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.
- Shrink Ratio: 2:1
- Dielectric Strength: 455 V/mil
- Shrink Temperature: 660° F
- Temperature Range: -325° to 500° F
- Flexibility: Semi-Rigid

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 Expandable Sleeving
Protect cable, hose, and pipe from abrasion and cuts in high temperature environments—this sleeving withstands temperatures over 450° F. It expands to fit over items for easy installation; sleeving then tightens around its contents for a secure fit. The braided construction permits heat and moisture to dissipate.
PTFE and PEEK sleeving withstand chemicals and salt water, so they can be used in extreme environments where cable and hose need protection from harsh fluids, such as in chemical plants and in oil and gas production. It has better abrasion and tear resistance than fiberglass sleeving. PTFE sleeving also withstands acids and solvents. PEEK is lighter in weight than PTFE, and more cost efficient.
High-Temperature Tube Sleeving
Use this sleeving in applications where temperatures reach up to 500° F. Made of PTFE, it resists chemicals, acids, and solvents. It meets UL 94 V-0 for flame retardance. Due to its small size and flexibility, it’s also known as spaghetti tubing. Because this sleeving is non-expandable, it does not stretch, so it’s best for applications where you know the exact diameter of the items you need to protect.
