Product Description

4:1 Flexible Dual Wall Heat Shrink Tubing

4X Flexible Dual Wall Heat Shrink Tubing,High Shrink Ratio tubing, Adhesive Lined Flexible Polyolefin Tubing, 4:1 shrink ratio tube

Model: DHST-FA

Application:

4:1 Flexible Dual Wall Heat Shrink Tubing is a High-Shrink-Ratio, Adhesive-Lined Flexible 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: 105℃
> Color: Black,Clear,etc
