Yellow polyolefin heat-shrink tubing on spool, thin wall 2:1 ratio

3M

3M FP301 Heat Shrink Tube Thin Wall 2:1 Yellow 100 ft

SKU CH-Q765-EQP6W

Thin-wall polyolefin tubing shrinks 2:1 to insulate and protect cables from -67 °F to 275 °F

  • TypeCable Management & Conduit
  • Thin-wall polyolefin shrinks to half diameter for tight wire protection
  • 2:1 shrink ratio covers 500–1000 MCM conductors with a single tube
  • Flame-retardant material resists acids, alkalis and solvents in harsh environments
  • Operates from –67 °F to 275 °F with 600 V dielectric strength
  • 100 ft spool lets you cut exact lengths for any job

Thin-Wall Heat-Shrink Tubing 100 ft

3M FP301 thin-wall heat-shrink tubing comes in a 100 ft yellow spool. The polyolefin material is flexible, flame-retardant and free of adhesive lining. It suits electrical professionals and installers who need reliable insulation for large conductors. The 2:1 shrink ratio reduces the inner diameter from 2 in to 1 in when heated.

Acid- and Solvent-Resistant Construction

After shrinking the wall thickness measures 0.05 in, providing a tough barrier that resists acids, alkalis and solvents. The tubing operates continuously from -67 °F to 275 °F and begins to shrink at 212 °F. Cut-to-length packaging lets users take exactly what each job requires without waste. Dielectric strength is rated at 600 V.

Fits 500–1000 MCM Wire Sizes

This size covers wire gauges from 500 MCM up to 1000 MCM, so it will not fit smaller conductors. Buyers working with lighter-gauge wire should select a different diameter. The yellow colour aids circuit identification in complex panels. No adhesive liner means a separate sealant is needed for environmental sealing.

Questions about this item

What does the 2:1 shrink ratio mean for the 2 in. inside diameter?

The tubing shrinks from 2 in. to 1 in. inside diameter when heated, giving a 2:1 reduction.

What minimum inside diameter must a connector have to pass through the unshrunk tubing?

The tubing ships with a 2 in. inside diameter, so any connector must fit through that opening.

What minimum temperature is required to shrink the tubing, and what tool is typically used?

A heat source reaching at least 212 Degrees F, such as a heat gun, is needed to activate shrinkage.
