Alpha FIT 321V Non Adhesive Tubing

Alpha FIT 295 Heat Shrink Tubing

This page focuses on the Alpha FIT 321V heat shrink tubing. It's a 3 to 1 shrinkable tubing manufactured with flame retardant irradiated polyolefin and a temperature range of -55°C to 125°C. It's most commonly used for general purpose protection and repair, where additional shrinage is needed, delicate and intricate electronics, insulation from environment, reduced longitudinal shrinkage and resistance to water, fungus and UV light.

In the manufacturing process FIT 321V 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. It comes in black and white colors.
