2:1 Black General Purpose Heat Shrink Mini Reel Bundle

Stock your bench with the heat shrink sizes you're actually likely to use.

This 2:1 Black General Purpose Heat Shrink Mini Reels Bundle combines six of our most useful tubing sizes in one practical pack, giving you a ready-to-use selection covering cable and object diameters from approximately 2.9mm right through to 20.3mm.

Unlike pre-cut assortment kits, each size comes on a proper mini reel, giving you several metres of tubing to cut to exactly the length you need. In total, the bundle includes 43 metres of black 2:1 heat shrink tubing.

The 2:1 shrink ratio makes this a versatile choice for everyday insulation, protection, bundling and cable finishing. The flexible single-wall polyolefin tubing is non-adhesive, making it particularly useful for electrical wiring, cable harnesses, machinery, automotive work and general workshop applications.

Ideal for electricians, installers, automotive wiring, electrical repairs, workshops, machinery and general maintenance.

Why This Selection?

We've deliberately chosen six popular sizes that work particularly well together, with continuous practical coverage from smaller cables through to much larger wiring, joints and components.

The 4.8mm-25.4mm selection focuses on the sizes our customers buy most frequently, while also giving plenty of overlap between neighbouring sizes. The result is a versatile range suited to the majority of everyday electrical, automotive and workshop jobs, without filling the bundle with very small sizes that may see less regular use.

Please note: The recommended diameter ranges are intended as a practical sizing guide. If the tubing needs to pass over a connector, crimp or other component before shrinking onto the cable, always check the diameter of the widest point as well.
