  • TypeCable Management & Conduit
  • ColorBlack
  • 3:1 shrink ratio seals 4 AWG to 3/0 AWG wire
  • Adhesive-lined polyolefin resists moisture, abrasion, acid and alkali
  • Thin 0.04 in wall after shrink keeps bundles compact
  • Operates from -67 °F to 230 °F for harsh environments
  • Ten 6 in black pieces ready for immediate use

What you get

Ten pieces of 3M EPS300 heat-shrink tubing, each six inches long and three-quarter inch diameter before shrinking. The polyolefin sleeve carries an inner adhesive layer and shrinks to a quarter inch, sealing wire sizes from 4 AWG up to 3/0 AWG.

Before you order

Confirm the cable bundle fits within the 0.75 in pre-shrink bore and that the final 0.25 in diameter will still clear any connectors. Check you can apply at least 250 degrees F to activate the shrink and adhesive flow.

Build and daily use

Thin-wall polyolefin resists abrasion, acid and alkali while remaining flexible after shrinking. The adhesive lining bonds to insulation and connector bodies, giving a moisture-resistant seal that stays intact from -67 to 230 degrees F.

Questions about this item

Does the pack contain ten six-inch pieces, or do I need to buy the tubing by the roll?

The package supplies ten individual six-inch lengths, each 0.75 in inside diameter before shrinking, so no separate roll is required.

The listing shows a 3:1 shrink ratio — how do I know if that covers my 4 AWG to 3/0 AWG wires?

The 3:1 ratio reduces the 0.75 in inner diameter to 0.25 in after shrinking, matching the stated 4 AWG to 3/0 AWG range.

The minimum shrink temperature is 250 °F — will a standard heat gun reach that without damaging the adhesive liner?

Yes, 250 °F is well within normal heat-gun output, and the adhesive-lined polyolefin is rated from -67 °F to 230 °F continuous use.
