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.
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.

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.

Heat-Shrink Cable Splitters
- Material: Polyolefin Plastic
- Shrink Ratio: See Table
- Shrink Temperature: 250° F
- Temperature Range: See Table
Also known as breakout boots, these splitters insulate and seal the point where wire splits off from cable. An adhesive lining melts when the splitter is heated and bonds to the underlying surface, creating a water-resistant seal.

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.
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.
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.
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.
