Ten six-inch black polyolefin heat-shrink tubes, thin-wall 2:1 ratio

3M

3M FP301 3/32" Black Heat Shrink Tube 6" 10-Pack

SKU CH-6P4P-3J2MW

Thin-wall polyolefin tubing shrinks 2:1 to insulate 28-26 AWG wires, resisting flame, acids, alkalis and solvents from -67 to 275 °F

  • Product typeCable Management & Conduit
  • 2:1 shrink ratio fits 28 to 26 AWG wire
  • Flame-retardant polyolefin withstands -67 to 275 °F
  • Acid, alkali and solvent resistant for harsh environments
  • 600 V dielectric strength protects electrical connections
  • Ten six-inch pieces ready for immediate use

3M FP301 3/32" heat-shrink tubing

This pack contains ten black polyolefin tubes, each six inches long, with a 2:1 shrink ratio. The tubing fits 28 AWG to 26 AWG wire and shrinks from a 0.09 in inside diameter to 0.05 in. It is flame retardant, acid and alkali resistant, and solvent resistant. No adhesive lining is present.

Thermals, noise and power draw

As a passive component, the tubing produces no noise and draws no power during use. It operates continuously across a temperature range of -67 °F to 275 °F. Minimum shrink temperature is 212 °F. Dielectric strength is rated at 600 V for electrical insulation.

Sustained-load behaviour

Under prolonged thermal exposure within its rated range, the material remains flexible and retains its flame-retardant, solvent-resistant properties. The thin wall measures 0.02 in after shrinking. It is not suited for wires larger than 26 AWG or applications requiring adhesive-lined sealing.

Questions about this item

How do I install the 3M FP301 3/32" heat shrink tube and what step do people often miss?

Slide the 6-inch tube over the 28 to 26 AWG wire, then apply heat until it shrinks from 0.09 in to 0.05 in ID; the step often missed is reaching the minimum 212 °F shrink temperature so the 2:1 ratio fully activates.

What maintenance or replacement will the 3M FP301 heat shrink tube need later?

The polyolefin tubing is acid, alkali and solvent resistant with no adhesive liner, so it requires no routine maintenance; replace only if physical damage breaches the 0.02 in recovered wall or the 600 V dielectric rating is compromised.

What limit appears first on the 3M FP301 tube during sustained high-temperature use?

Continuous exposure above the 275 °F upper temperature rating will degrade the material before the 600 V dielectric strength or 2:1 shrink performance becomes an issue.
