Alpha Wire Heat Shrink Tubing, Black 1.17mm Sleeve Dia. x 152mm Length 2:1 Ratio, FIT-221 Series

The FIT-221 range of heat-shrink tubing offers a reliable way to protect and seal electrical terminations or add extra durability to a cable.

The FIT range of heat shrinkable tubing is made from premium materials under tight manufacturing conditions. This means that FIT heat-shrink tubing has excellent physical characteristics such as wide temperature ranges and low longitudinal shrinkage.

Heat shrinkable tubing

FIT-221 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.

For a secure fit, it is necessary that the tubing's recovered diameter (the diameter after shrinkage) is smaller than the diameter of the area to be insulated. At the same time, the tubing's expanded diameter (the diameter before shrinkage) needs to be large enough to fit easily over the area to be insulated, as well as any connectors attached to it.

Polyolefin is a polymer which is often used in heat shrink tubing as it has excellent mechanical and electrical properties. Polyolefin is also flexible, fast-shrinking and can be manufactured in a wide range of colours.
