Dual Wall Heat Srhink Black on Lug Cable EndsOur glue lined dual wall heat shrink tube is a high quality grade of heat shrink used to create a permanent waterproof barrier & environmental seal for electrical connections.

Often used as an alternative to moulded parts and/or breakouts this grade of heat shrink tube has a high shrink ratio to make installation easy.

This page lists all our standard sizes of Black, Dual Wall Adhesive Lined Heat Shrink that are available in 1.2mtr long lengths. 

Our online store also has this same grade of heat shrink in red pre-cut lengths as well as bulk rolls in both red and black colours. Links to the pages for each of these styles are included at the bottom of this page.

Benefits and Characteristics of our Dual Wall, Adhesive Lined Heat Shrink Tube.

This kit is made up from high quality, industrial grade heat shrink which has a number of benefits. These include:

Large Shrink Ratio.

Having a 3:1 shrink ratio is ideal for creating a good, water-tight barrier around irregular connections and terminations. It also enables you to seal and insulate around the connection to a lug or link barrel with ease.

Flame Retarded and Self-Extinguishing.

Our Dual Wall Heat Shrink is both self-extinguishing and flame retarded. It has been tested for flammability in accordance with UL 224 VW1.

Excellent Environmental Protection and Resistance.

Adhesive Lined Dual Wall Heat Shrink Tube has very good chemical resistance, resists copper corrosion and is also UV stabilised for long-term performance outdoors. This type of insulation tube has a low water absorption rate of 0.15%.

This grade of heat shrink also has excellent temperature resistance. Tested in accordance with IEC requirements, our Dual Wall Heat Shrink has a continuous operating temperature range of -55°C to +125°C. This ensures in remains flexible in low temperatures whilst simultaneously withstanding elevated heat environments.

Good Electrical Properties and Mechanical Strength.

Dual Wall Heat Shrink has a dielectric strength rating of >15kV/mm. It also has good tensile strength and elongation characteristics. In general, it’s a tough, resilient insulation that will provide excellent insulation and mechanical protection for cable joins and connections.

Typical Uses for Dual Wall Glue Lined Heat Shrink Tube.

  • Waterproof sealing of electrical connections in the automotive and marine industries.
  • Insulating and sealing RF cable joins and terminations.
  • For colour coding cables and cable ends.
  • Insulating and sealing around lug and palm link connections.
  • Strain relief for terminations.
  • As an alternative to moulded parts.
  • For cable breakouts.
