Kable Kontrol® 4:1 - 1" Inside Diameter over-expanded polyolefin heat shrink tubing is flexible, flame-retardant, and used for specialty applications that include cable jacket retrofitting and repair, as well as the electrical insulation of wire assemblies with oversize components or connectors. The over-expanded product fits easily over the end of a connector and shrinks down to 25% of its original diameter to fit snugly over both the connector and any narrower attached wires.
