Heat Shrink Tubing

Heat Shrink Tubing

Our heat shrink tubing provides electrical insulation, mechanical protection, sealing, and strain relief, and it can also be used to identify components and wires, creating a functional, professional appearance of the assembly.

Our heat shrink tubing is a valued option for insulation, protection, and sealing when compared to taping, molding, or potting.  When heated, the heat shrink tubing conforms to the size and shape of the substrate beneath for quick and easy installation. Heat shrink tubing is available in a wide variety of materials, colors, and sizes, and is delivered in easy-to-use forms such as spools, 1.2m lengths, and cut pieces. We can help you select the best product for your application to optimize performance and installation, providing a reliable and robust solution. We also offer customized products to enhance product handling, installation and logistics. 


Ultra-high shrink rate tubing offers heat shrink ratios up to 8:1


RoHS-compliant products for automotive application, and consumer-goods


Survives high-temperature excursion up to 260°C.

High-Shrink Ratio

For Maximum Sealing and Protection

Using radiation crosslinking polymers and processes we pioneered, our heat-shrinkable tubings are made of polyolefins, fluoropolymers and elastomers enhanced by radiation cross-linking providing a memory effect and heat-stability. When heated during installation, our tubings shrink to conform to the shape of the substrate on wihc they are installed. These provide dependable insulation, mechanical protection, and strain relief, as well as aesthetic appeal.

Single wall tubings are available in thin wall, medium wall and thick wall versions. With dual wall tubings, an inner wall — either an encapsulant or an adhesive — melts and flows during installation heating, to protect against environmental damage. Encapsulants protect connections and components from splashes and corrosion. Adhesives go a step further, sealing to plastic, metal, rubber or other substrates. You can choose from heat shrink tubings that are highly flexible or semirigid, designed for operation in high- or low-temperature environments, and flame retardant to meet a range of industry standards. They are also offered in various colors.

Environmentally seals protect a wide variety of electrical applications, including back-end connector sealing, breakouts and connector-to-cable transitions. High expansion ratio makes it possible to repair most damaged cable jackets without removing connectors.

Tubing Comparison

Single Wall vs Dual Wall

TE's single wall tubing provides superior insulation, strain relief, and protection against mechanical damage and abrasion. Benefits include:

  • Reliably consistent dimensions and physical properties
  • Meets SAE-AMS-DTL-23053, MIL-PRF-46846, and VG95343 standards
  • Some products are UL recognized / CSA certified 


TE's dual wall tubing seals and protects against the ingress of dust and fluids. TE's Raychem dual wall tubing uses an adhesive lining that melts and flows during installation, creating a moisture-resistant protective barrier. Benefits include:

  • Controlled amounts of adhesive and consistent results
  • Compliance with SAE-AMS-DTL-23053
  • Some products have UL recognition / CSA certification
  • Selected tubings are type-approved by the American Bureau of Shipping (ABS) and Lloyd’s Registry of Shipping
