This heat shrink tubing, sold in 1 meter lengths, shrinks down to one third of its original diameter when heated (3:1 ratio). It is also known as dual wall heat shrink and has an adhesive lining on the inside that melts for a watertight seal. Versatile and flame retardant, it provides good adhesion to metals, polyolefin, and PVC. With an operating temperature range of -55 to +110°C and a shrink temperature of 110°C, it offers excellent electrical insulation and resistance to common fluids and solvents. Plus, its flexibility and abrasion resistance make it perfect for irregular shapes.
