About Heat-Shrink Tubing
More
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.
Use flexible tubing in applications where wire and cable need to bend around curves and corners. Semi-rigid tubing bends only slightly. Rigid tubing will not bend. Use it with wire and cable that do not need to bend, such as in straight runs.
SAE AMS-DTL-23053/4 Class 1 tubing meets requirements for material quality and color.
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.

Extra-Thick Moisture-Seal Heat-Shrink Tubing
- Material: Polyolefin Plastic
- Shrink Ratio: 3:1
- Dielectric Strength: 500 V/mil
- Shrink Temperature: See Table
- Temperature Range: -65° to 230° F
Extra-thick walls provide better protection against abrasion and tears than standard moisture-seal tubing. It has an adhesive lining that melts when the tubing is heated and bonds to the underlying surface, creating a water-resistant seal.
Short-length tubing is good for sliding over terminals, wire ferrules, and compression lugs to insulate and protect them.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.

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.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.

High-Shrink-Ratio Moisture-Seal Heat-Shrink Tubing
- Material: Polyolefin Plastic
- Shrink Ratio: 5.6:1
- Dielectric Strength: 200 V/mil
- Shrink Temperature: 245° F
- Temperature Range: -65° to 190° F
- Specifications Met: AMS-DTL-23053
Create a tight, water-resistant seal over irregularly shaped components. When heated, this tubing shrinks down to about 1/6th of its original ID, while an adhesive lining melts and forms a barrier around your component. For better protection against scrapes, tears, and punctures, it has thicker walls than standard tubing. And since it’s made from polyolefin, this tubing is a good pick for most other environments as well.
Dielectric strength is the maximum voltage a material can handle before it starts to break down. The higher the dielectric strength of a material, the better it is for preventing electricity, heat, or signal from dissipating from wire and cable.
Tapered Heat-Shrink Tubing
- Material: Polyolefin Plastic
- Shrink Ratio: See Table
- Dielectric Strength: 200 V/mil
- Shrink Temperature: 250° F
- Temperature Range: -65° to 275° F
A different shrink ratio on each end allows this tubing to fit over cable assemblies and wire harnesses with large connections, or around connectors with a 90° elbow. An adhesive lining melts when the tubing is heated and bonds to the underlying surface, creating a water-resistant seal. The tubing length listed is after shrinking; the length before shrinking is 20-25% shorter.
Lipped tubing has a ridge on the inside of one opening for better retention than non-lipped tubing. It’s often used with grooved adapters—upon shrinking, the lip grips onto the groove.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.

Heat-Shrink End Caps
- Material: Polyolefin Plastic
- Shrink Ratio: See Table
- Shrink Temperature: 250° F
- Temperature Range: -65° to 230° F
Seal the end of crimped connections, such as motor coils, to insulate and protect them from moisture and abrasion. These caps have an adhesive lining that melts when the cap is heated and bonds to the underlying surface, creating a water-resistant seal. You can also use them to seal the ends of pipes and wire rope.
Caps with a pressure-relief valve let you monitor pressure changes and release gases that build up due to changes in temperature and humidity.

Wrap-Around Heat-Shrink Tubing
Protect wire and cable without disconnecting them from an assembly. This tubing is ideal for adding protection to damaged components that are hard to rewire. For a water-resistant seal, it has an adhesive lining that melts when heated to bond the tubing to the underlying surface. It meets ASTM requirements for flame retardance.
Tubing with an adhesive strip closure is easy to install. Simply peel off the paper backing, wrap the tubing around your components, seal the adhesive strip, and shrink it. Use this tubing to protect smaller components or bundles of wiring. It meets military specifications for material quality and color.
Tubing with a locking channel closure gives you more secure protection than tubing with an adhesive strip closure. It’s ideal for protecting larger components in applications that demand a strong seal, such as industrial construction and automation systems. To install, wrap the tubing around your components and insert the stainless steel locking channel to hold the tubing together. Then shrink the tubing from the center to the ends. After shrinking, you can leave the locking channel on or remove it, depending on your application.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.

Moisture-Seal Wrap for Heat-Shrink Tubing
Use this wrap with heat-shrink tubing to create a moisture-resistant seal. Apply it like tape around wire and cable, and slide the tubing over the wrap. The wrap melts when tubing is heated and bonds to the underlying surface.
TPE rubber wrap has a higher dielectric strength than nylon plastic and butyl rubber wrap, so it’s the best choice for electrical insulation.
Nylon plastic wrap is ultra thin, so you can wrap it around each individual wire as well as your whole bundle for enhanced protection. Along with water, it resists oils, chemicals, and grease.
Butyl rubber wrap seals larger gaps than TPE rubber and nylon plastic wrap, so it’s better for protecting irregular shapes or items with deep grooves. However, it doesn’t withstand temperatures as high.
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.
