Clear heat-shrink tube on spool, 1 in diameter, 50 ft length

3M

3M FP301 1 in Clear Heat Shrink Tube 50 ft

SKU CH-V1DN-SEH2S

Clear heat-shrink tubing shrinks 2:1 to .5 in I.D., resists acids, solvents and flame, and operates from -67 to 275 °F

  • TypeCable Management & Conduit
  • Clear identification with transparent polyolefin
  • 2:1 shrink ratio halves diameter to .5 in
  • Flame-retardant material withstands -67 °F to 275 °F
  • Acid, alkali and solvent resistant for harsh environments
  • 600 V dielectric strength insulates up to 500 MCM wire

1-inch Clear Heat Shrink Tubing

This 3M FP301 tube is a thin-wall polyolefin sleeve that shrinks 2:1 from 1 in to .5 in. It suits electricians, automotive technicians and hobbyists who need clear, flexible insulation for wire sizes 4/0 AWG to 500 MCM. The 50 ft spool is cut to length for custom jobs.

Replaces worn or missing insulation

Use it when existing sleeving has cracked, melted or been stripped away during repairs. The jump is worth it if you need flame-retardant, acid- and solvent-resistant cover that withstands -67 to 275 Degrees F and 600 V dielectric strength. It will not help buyers who want adhesive-lined seal or a heavier wall.

Shrinks with a heat gun

Apply heat at or above 212 Degrees F until the tube conforms. The thin .04 in wall recovers quickly, so overheating can split the material. Work in a ventilated area and keep the flame moving; uneven heating leaves loose sections that slide off later.

Questions about this item

What size opening fits over a 1 in diameter wire before I shrink this tubing?

The supplied inner diameter is 1 in before shrinking, so it slides over a 1 in wire or bundle.

What is the minimum heat temperature and the step most people skip when installing this thin-wall polyolefin tube?

Apply at least 212 °F evenly around the tube; the step often missed is rotating the heat source so the 2:1 shrink ratio closes uniformly without hot spots.

How often should I inspect or replace this clear heat-shrink after it has been shrunk in place?

The material resists acids, alkalis and solvents from -67 °F to 275 °F, so inspect only if the installation sees physical damage or temperatures beyond that range.
