280-Piece Heat Shrink Tubing Kit

This kit supplies 280 pieces of polyolefin heat shrink tubing across nine sizes and colours. The 2:1 shrink ratio reduces each tube to half its original diameter when heated. All pieces measure 45 mm in length before shrinking. It is designed for insulating and protecting wire connections in automotive and general electrical work.

For technicians bundling mixed-gauge wiring

The assortment covers diameters from 1.5 mm up to 12 mm, making it suitable for jobs that require several sizes at once. Buyers who need only a single diameter or a different shrink ratio should consider a dedicated pack instead.

2:1 shrink ratio defines coverage

Each tube shrinks to exactly half its supplied diameter, so the chosen size must be large enough to slide over the connector before heating. If the application demands a tighter or looser recovery ratio, this kit will not match the requirement.
