Heat Shrink Tubing - Dual Wall

Dual Wall Heat Shrink Tubing

The general purpose dual wall (GPDW) includes an adhesive layer, hence the name, to improve the strength of the seal. The product shrinks when heated to 33% (3:1) of the original diameter, for dual wall tubing. A typical heat gun can be used to activate the tubing with temperatures starting as low as 250°F (121°C). Temperatures in excess of 347°F (175°C) may destroy the effectiveness of the tubing. Dual wall is especially useful for moisture-proof, high-humidity requirements. With our central U.S. location, ordering and shipping within the USA can be as fast as 4-5 days.
