2:1 Heatshrink

2:1 ratio heatshrink tubing (heat shrink) for insulating, protecting and tidying electrical connections, cables and wiring. When heated it shrinks to half its original diameter, giving a snug insulated finish over joints, terminals and cable bundles. This is the standard, most widely used shrink ratio, available in black and mixed colours, single sizes and assorted boxes. Ideal for automotive, electrical and general wiring. Available in a range of diameters, with trade prices and UK delivery.
