About Heat-Shrink Tubing

Moisture-Seal Heat-Shrink Tubing
Create a water-resistant seal—this tubing has an adhesive lining that melts when the tubing is heated and bonds to the underlying surface. Choose tubing with a larger shrink ratio to cover irregularly shaped objects or cable assemblies that have a large size difference between the cable and connector.
Rigid tubing will not bend. Use it with wire and cable that do not need to bend, such as in straight runs.
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.

Chemical-Resistant Moisture-Seal Heat-Shrink Tubing
- Material: PVC Plastic
- Shrink Ratio: 2:1
- Dielectric Strength: 1,000 V/mil
- Shrink Temperature: 215° F
- Temperature Range: 0° to 220° F
Made of PVC, this tubing resists chemicals, oil, and solvents. An adhesive lining melts when the tubing is heated and bonds to the underlying surface, creating a water-resistant seal. It resists UV, so it won’t fade or discolor when exposed to sunlight.

Chemical-Resistant Heat-Shrink Tubing
Use this tubing where wire and cable may be exposed to chemicals, oil, and acids.
PVC plastic tubing is more chemical resistant than rubber. It also resists UV, so it won’t fade or discolor when exposed to sunlight. Store tubing at 70° F or lower to avoid premature shrinkage.
SAE AMS-DTL-23053/1 Class 2, 23053/2 Class 2, and 23053/13 tubing meets requirements for material quality and color.
Flame rated VW-1 tubing meets requirements for preventing the spread of flames based on a timed test with vertically suspended material.
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.

No-Heat Shrink Tubing
Create a permanent seal without applying heat. Also known as cold-shrink tubing, this tubing has a removable spiral-wound core. Slide the tubing over wire and cable and pull out the core. When the core is removed, the tubing contracts and conforms to the underlying cable. The length shrinks by several inches. Made of rubber, it resists chemicals including acids, alkalies, and ozone. Resistant to UV, it won’t fade or discolor when exposed to sunlight.
EPDM rubber tubing resists tearing and abrasion better than silicone rubber tubing, making it more durable. It meets ANSI C119.1 for water seal requirements and can be submerged.
Silicone rubber tubing withstands a wider temperature range without degrading than EPDM rubber tubing. It is also more flexible for use in tight spaces.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.

No-Heat Shrink End Caps
- Material: EPDM Rubber
- Shrink Ratio: See Table
- Temperature Range: -40° to 220° F
With a spiral-wound core, these end caps form a permanent seal on the end of your crimped wire or cable without heat or tools. Slide them on, pull out the core, and they conform to the end of your connection, creating a seal that insulates and protects against water, dust, and abrasion. You may also know them as cold-shrink tubing end caps. They’re sometimes even used to seal the ends of pipes and wire rope.
Made of EPDM, these caps won’t become brittle from ozone or chemicals such as acids and alkalies. They also won’t fade in the sun.
