Heat-Shrink Tubing
Use this general purpose polyolefin tubing to create a tight, custom-fit insulation to protect wire and cable.
SAE 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.

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.
Semi-rigid tubing bends only slightly. 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 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.

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.

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.
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.
