Thin-wall heat shrink for wire protection

This 3M EPS300 tubing provides a 3:1 shrink ratio and an adhesive lining that seals against moisture and contaminants. The red polyolefin material is flame retardant and rated from -67 to 230 degrees Fahrenheit. Each pack contains ten individual six-inch pieces sized for 4 AWG to 3/0 AWG conductors.

Verify wire gauge and shrink temperature

Confirm that your conductors fall within the 4 AWG to 3/0 AWG range so the 0.75 inch inner diameter shrinks down to 0.25 inch. Ensure your heat source can reach the minimum 250 degree Fahrenheit shrink temperature for full adhesive activation. The 0.04 inch recovered wall thickness adds abrasion and chemical resistance.

Maintains seal through thermal cycling

The adhesive lining flows during shrinking and sets to a durable bond that resists vibration and temperature swings across the full rated range. Polyolefin construction remains flexible after recovery, preventing cracks that could expose conductors. Flame-retardant properties persist under sustained load without degrading the seal.

Questions about this item

Does the 10-pack of 6-inch red heat-shrink tubes include any tools or connectors, or must I buy a heat gun separately?

The pack contains ten individual 6-inch pieces of adhesive-lined polyolefin tubing; a heat source capable of reaching 250 °F is required and is not included.

How do I decide between the 3/4-inch and other diameters for a 4 AWG to 3/0 AWG wire job?

The 0.75-inch pre-shrink diameter covers the full 4 AWG to 3/0 AWG range and shrinks to 0.25 inch, so choose this size when your conductor falls inside that wire gauge window.

What does the 3:1 shrink ratio mean once the tube is heated on a live cable?

A 3:1 ratio means the 0.75-inch tube shrinks down to 0.25 inch, producing a 0.04-inch wall that seals, insulates and resists abrasion from -67 °F to 230 °F.
