Heat-shrink tubing gives you more choices to achieve reliable, rugged cabling systems. Heatshrink provides an easy solution to colour coding wires for easy circuit identification or make fast, reliable repairs to nicked or worn insulation.

Silicone rubber has excellent resistance to extreme temperatures and does not react with most chemicals due to it being a highly inert material.
