Alpha FIT 400 FEP Heat Shrink Tubing

Alpha FIT 400 FEP Heat Shrink Tubing

This page focuses on the Alpha FIT 400 heat shrink tubing. It's a 1.2 to 1 shrinkable tubing manufactured with FEP PTFE material with a temperature range of -67°C to 200°C. It's most commonly used for fiber optic applications, high temperature cables, limited space applications, digital electronics and in extremely caustic environments.

In the manufacturing process FIT 400 Telon heat shrink tubing features excellent chemical resistance, extreme temperature range, thinnest wall thickness, unmatched dielectric properties and lower recovery temperature than TFE PTFE tubing. Alpha Wire recommends using the FIT 400 shrinkable tubing with their Xtra Guard 4 and Xtra Guard 5 material.
