3M EPS300 1 1/2 in 48 in Black 5 pcs Heat Shrink Tubing

SKU CH-WAY7-BTSKG

Adhesive-lined polyolefin tubing shrinks 3:1 to seal and protect wires from 3/0 AWG to 400 MCM, resisting abrasion, chemicals and temperatures from -67 to 230 °F

  • 3:1 shrink ratio seals large cables
  • Adhesive lining bonds and waterproofs connections
  • Flame-retardant polyolefin resists heat to 230 °F
  • Abrasion and chemical resistant for harsh environments
  • Five 48-inch black pieces ready to use

1.5 in Black Heat Shrink Tubing

This adhesive-lined polyolefin tubing shrinks at a 3:1 ratio from 1.5 in to .51 in inner diameter. It fits wire sizes from 3/0 AWG up to 400 MCM. Each piece measures 48 in long and the pack contains five pieces. The thin wall design provides abrasion and chemical resistance for electrical insulation.

Sustained heat and chemical exposure

The material withstands continuous temperatures from -67 to 230 degrees F without degrading. Flame retardant properties and acid and alkali resistance maintain seal integrity during prolonged thermal cycling and harsh environments. Adhesive lining creates a permanent moisture barrier that does not break down under sustained load.

Minimum shrink temperature and wall thickness

A minimum shrink temperature of 250 degrees F activates the adhesive and full recovery. After shrinking the wall thickness measures .1 in providing mechanical protection while remaining flexible. The thin wall construction keeps added bulk low for tight installations.

Questions about this item

How much heat does the 3M EPS300 tubing need to shrink fully during a long job?

The minimum shrink temperature is 250 degrees F, so a standard heat gun on its low setting will activate the adhesive liner without overheating nearby wires.

What wire gauges must I already have on hand for the 1.5 in tubing to fit correctly?

The tubing is rated for use with wire sizes from 3/0 AWG up to 400 MCM, so any cable in that range will slide inside the 1.5 in bore before shrinking.

Will the shrunken 0.51 in diameter still seal older cables that have slightly damaged insulation?

Yes, the 3:1 shrink ratio and adhesive lining create a watertight seal down to 0.51 in, filling gaps on aged insulation while staying flexible at -67 degrees F.
