Heat-shrink tubing with black adhesive 6mm per meter

Black heat-shrink tubing with adhesive inner wall, Ø 6 mm before shrinking and Ø 2 mm after free shrinking, 3:1 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 that bonds to the cable, more resistant to moisture than a simple single-wall tubing that only constricts.

Choosing the right diameter

The Ø 6 mm must fit over the widest point to be covered, and the Ø 2 mm after shrinking must be smaller than the support so the tubing grips. Between these two values, the 3:1 ratio provides a comfortable adjustment range.

What this datasheet does not state

Hardware fitting 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 waterproofing, engine harness, contractual use — use the TE Connectivity ATUM range from the catalog, documented (UL E85381, AMS-DTL-23053/4, −55 °C to +110 °C).
