Ten black adhesive-lined heat shrink tubes 1.5in by 6in

3M

3M EPS300 1.5 in 6 in Black 10 Pcs Adhesive Heat Shrink Tube

SKU CH-BD79-REK9J

Adhesive-lined polyolefin heat-shrink tubing shrinks 3:1 to seal and protect wires from 3/0 AWG to 400 MCM, resisting flame, abrasion, acids and alkalis across a -67 °F to 230 °F range

  • TypeCable Management & Conduit
  • 3:1 shrink ratio seals 1.5 in down to .51 in for tight wire protection
  • Adhesive lining bonds at 250 °F creating waterproof seal from -67 °F to 230 °F
  • Flame-retardant polyolefin resists abrasion, acid and alkali in harsh environments
  • Thin .04 in wall keeps assemblies compact while maintaining dielectric strength
  • Pack of 10 black 6 in pieces covers 3/0 AWG to 400 MCM wire range

What this heat-shrink tubing does

This adhesive-lined polyolefin tube shrinks to seal wire splices and terminals against moisture and mechanical wear. The 3:1 ratio lets one size cover wire gauges from 3/0 AWG up to 400 MCM. Ten six-inch black pieces are supplied for automotive, marine or industrial maintenance jobs.

Build quality and daily handling

Thin-wall construction keeps the sleeve flexible before and after shrinking, while the inner adhesive layer bonds to insulation when heated. Flame-retardant material meets common safety requirements for vehicle and equipment wiring. Individual pieces are easy to store and cut to length on site without special tools.

Practical limits of the 3:1 shrink ratio

The tube starts at 1.5 in inside diameter and finishes at 0.51 in with a 0.04 in wall thickness. It activates at 250 °F and remains stable from -67 °F to 230 °F. Connections larger than 400 MCM or environments exceeding the temperature range will need a different sleeve specification.

Questions about this item

How does the 3:1 shrink ratio affect the final size of the 1.5 in tubing?

The tubing shrinks from 1.5 in down to 0.51 in inside diameter, giving a tight seal on wires from 3/0 AWG to 400 MCM.

What clearance is needed for the 6 in length and 0.04 in recovered wall?

Each piece is 6 in long and recovers to a 0.04 in wall, so allow space for the full length and the thin profile in tight bundles.

What temperature and method should I use to shrink the adhesive-lined polyolefin?

Apply heat at or above 250 Degrees F until the adhesive flows and the tube conforms; uneven heating leaves gaps in the seal.
