Heat Shrink Tubing - Dual Wall

The general purpose dual wall (GPDW) includes an adhesive layer, hence the name, to improve the strength of the seal. The product shrinks or recovers when heated, a 3-1 ratio or 33% of the original diameter, for dual wall tubing. Other ratings are available upon request. 

A typical heat gun can be used to activate the tubing’s main feature starting as low as 250°F (121°C) while temperatures in excess of 347°F (175°C) may tend to 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.
