Black 9mm heat-shrink tubing per meter

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

Single wall: implications

Non-adhesive tubing mechanically clamps the support without sealing it. This is suitable for sheathing, identification, and insulation repair. For a junction that must remain watertight — crimped terminal exposed, wet bulkhead passage — use adhesive tubing: the adhesive version is available in the same diameter.

Selecting the correct 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 clamps. Between these two values, the 3:1 ratio provides a comfortable adjustment range.

What this datasheet does not state

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 range. For applications where these guarantees matter — specified watertightness, 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).
