Versatile 28-Piece Heat Shrink Kit
The 3M FP301 kit supplies twenty-eight six-inch tubes in seven colours for electrical insulation and wire identification. Thin-wall polyolefin construction makes the tubing flexible and easy to handle during routine maintenance or field repairs. Electricians, automotive technicians and hobbyists can organise and protect connections from 22 AWG to 24 AWG wire. Acid, alkali and solvent resistance adds durability in harsh environments.
2:1 Shrink Ratio Decides Fit
A 2:1 shrink ratio means each tube halves its internal diameter when heated, so the same piece covers a range of wire gauges within the 22 AWG to 24 AWG window. The kit contains a single size of tubing, so buyers needing multiple diameters for larger cables must source additional assortments. Flame-retardant polyolefin meets general safety requirements without adhesive lining.
Operating Range From -67 °F to 275 °F
The material stays flexible down to minus sixty-seven degrees Fahrenheit and withstands continuous exposure up to two hundred seventy-five degrees Fahrenheit. Thin walls transfer heat quickly, allowing fast recovery with a standard heat gun while keeping surrounding components cool. No adhesive liner means clean removal if rework is required.

Questions about this item
What does the 2:1 shrink ratio mean when the tubing is heated on a wire?
The 2:1 ratio means each tube shrinks to half its original diameter, so a 6-inch piece tightens around 22 AWG to 24 AWG wire for a secure fit.
How does the polyolefin material perform at the temperature limits of -67 Degrees F to 275 Degrees F?
The thin-wall polyolefin stays flexible and flame-retardant across the full range, resisting acids, alkalis and solvents without adhesive lining.
Will the 6-inch sticks fit in a standard toolbox compartment?
Each 6-inch stick is short enough for most toolbox trays, and the 28-piece kit packs into a compact assortment of seven colours.
