Heat-shrink tubing with adhesive black 9mm per meter

Black heat-shrink tubing with adhesive inner wall, Ø 9 mm before shrinking and Ø 3 mm after free shrinking, 3:1 shrink ratio, sold per meter.

What the adhesive does

When installed, the inner wall melts and fills the gap between the tubing and the support. The result is a sleeve bonded to the cable, more resistant to moisture than a single-wall tubing that only tightens.

Choosing the right diameter

The Ø 9 mm must fit over the widest point to be covered, and the Ø 3 mm after shrinking must be smaller than the support so the tubing tightens. Between these two values, the 3:1 ratio provides a comfortable adjustment range.

What this datasheet does not say

Hardware reference without published manufacturer datasheet: the shrink ratio and diameters above come from the supplier catalog, but we have no certified temperature range, UL approval, or reference standard for this line. For applications where these guarantees matter — specified watertightness, engine harness, contractual use — use the TE Connectivity ATUM line from the catalog, documented (UL E85381, AMS-DTL-23053/4, −55 °C to +110 °C).
