Alpha FIT 221 Polyolefin Heat Shrink Tubing

Alpha FIT 221 Heat Shrink Tubing

This page focuses on the Alpha FIT 221 heat shrink tubing. It's a 2 to 1 shrinkable tubing manufactured with irradiated polyolefin with a temperature range of -55°C to 135°C. It's most commonly used for general purpose protection and repair, identification, beautifying substrates, insulation from environment, reduced longitudinal shrinkage and resistance to water, fungus and UV light.

In the manufacturing process FIT 221 heat shrink tubing is used with wire and cable harnesses, cable and connector protection and covering wire and cable splices to be sure that the conductor doesn't get water or damaged.
