Ten black 6-inch adhesive-lined heat-shrink tubes in a pack

3M

3M EPS300 3/8" Adhesive Lined Heat Shrink Tube Black 6" 10-pack

SKU CH-1GJ9-GC7P6

Adhesive-lined polyolefin tubing shrinks 3:1 to seal 12–8 AWG wires, resisting abrasion, acid and alkali from –67 °F to 230 °F

  • 3:1 shrink ratio seals 12-8 AWG wires
  • Adhesive-lined polyolefin resists moisture and corrosion
  • Flame-retardant material withstands -67 °F to 230 °F
  • Abrasion, acid and alkali resistant for harsh environments
  • Ten six-inch black pieces ready for immediate use

3M EPS300 Adhesive Lined Heat Shrink Tube

This pack contains ten pieces of black dual-wall heat shrink tubing designed for wire insulation and environmental sealing. Each piece measures six inches long and fits wire sizes from 12 AWG to 8 AWG. The adhesive liner melts during shrinking to create a moisture-resistant bond. It suits electricians and technicians needing reliable cable repairs or splices.

3:1 Shrink Ratio Polyolefin Construction

The tubing is made from flexible, flame-retardant polyolefin with a 3:1 shrink ratio for a tight fit over irregular shapes. Inner diameter shrinks from 0.38 in to 0.12 in, leaving a 0.03 in wall thickness after recovery. Abrasion and chemical resistance protect wires from acid, alkali and mechanical wear. Individual pieces allow precise cutting for each job.

-67 to 230 Degrees F Operating Range

Minimum shrink temperature is 250 Degrees F, activating the adhesive liner for a permanent seal. The wide temperature rating ensures performance in extreme cold and high-heat environments. Flame-retardant material adds safety in automotive or industrial settings. No special tools are required beyond a standard heat gun.

Questions about this item

What shrink ratio does the 3M EPS300 tubing provide, and what inside diameter does it reach after shrinking?

The tubing has a 3:1 shrink ratio, reducing the inside diameter from 0.38 in to 0.12 in after full recovery.

What wire gauge range and cut length does each piece in the 10-pack cover?

Each 6 in piece is suited for wire sizes from 12 AWG to 8 AWG.

What minimum temperature is needed to activate the adhesive liner, and what tool mistake should be avoided?

Apply at least 250 °F evenly around the tube; avoid concentrating heat in one spot, which can scorch the polyolefin before the adhesive flows.
