Heat-shrink tubing for 20–14 AWG wire

This thin-wall polyolefin tube shrinks at a 2:1 ratio from a 0.21 in inside diameter to 0.09 in. It covers wire gauges from 20 AWG up to 14 AWG and comes in a 4 ft black length. The material is flame-retardant and resistant to UV light.

Check wire gauge and heat source before ordering

Verify that your conductors fall within the 20 AWG to 14 AWG range so the 0.21 in bore will fit before shrinking. You need a heat gun or similar tool capable of reaching at least 158 Degrees F to activate the shrink. No adhesive lining is present, so the tube relies on friction alone.

Thin wall holds shape under continuous heat

After shrinking the wall measures 0.02 in thick and remains stable up to the 125 Degrees F operating limit. Dielectric strength is rated at 600 V, so insulation performance persists during sustained loads. The tubing does not melt or drip at the minimum shrink temperature of 158 Degrees F.
