Product Description

4:1 Semi-rigid Dual Wall Heat Shrink Tubing

4:1 Semi-rigid Dual Wall Heat Shrink Tubing,  Polyolefin Tubing for Automotive Wire Harnesses, Heat Shrink tubing SMS

Model: DHST-ES

Application:

4:1 Semi-rigid Dual Wall Heat Shrink Tubing is a High-Shrink-Ratio, Adhesive-Lined Semi-rigid Polyolefin Tubing. 4:1 shrink ratio allows a few sizes to cover a wide range of splice and component diameters, mechanically tough tubing provides strain relief and abrasion protection of wire splices, terminals, and other components, adhesive-lined against fluids, moisture and other contaminants.

> Longitudinal shrink ratio: ≤±8%
> Out jacket flame retardant, inner adhesive self-extinguished
> Continuous operating temperature: -45℃~ 125℃
> Shrink temperature: 125℃
> Color: Black, Clear, etc
