Additional Information

This adhesive-​lined shrink tubing – 3:1 – flexible Polyolefin has a minimum shrink temperature of 250°F (121°C), where it will quickly shrink down to 33% of its original size creating a skin tight, water resistant, seal. The environmental temperature of the 1/8 inch polyolefin heat shrink tube is -55°C (-67°F) to 110°C (230°F), however, adhesive reflow will occur at temperatures above 80ºC (176ºF). Nelco Products offers this 1/8″ adhesive lined heat shrink tubing in three different colors: Clear, black, and red. The black and red are UL Recognized.
