3M Heat Shrink Tubing 0.75in ID

This adhesive-lined polyolefin tubing shrinks at a 2:1 ratio from 0.750 inches to 0.375 inches inside diameter. The flexible black material carries a 600V rating and meets SAE-AMS-DTL 23053/4 standards for electrical insulation. Each pack contains five pieces measuring four feet in length.

Shrink Temperature and Voltage Limits

A minimum shrink temperature of 250 degrees Fahrenheit is required to activate the adhesive lining and achieve full recovery. The tubing operates continuously between -67 and 230 degrees Fahrenheit without flame-retardant properties. Exceeding the 600V maximum rating risks insulation breakdown in high-voltage applications.

Adhesive-Lined 2:1 Shrink Ratio

The dual-wall construction with hot-melt adhesive creates a moisture-resistant seal when heated correctly. This specification determines whether the tubing will encapsulate connectors and splices effectively for automotive or marine wiring. Buyers needing a higher shrink ratio or flame-retardant jacketing should select a different product.

Questions about this item

Should I pick the 0.75 in. ID 4 ft pack of 5 or a different size?

This pack gives you five 4 ft lengths of 0.75 in. ID tubing that shrinks to 0.375 in., covering 3 to 4/0 AWG; choose it when your cables fall in that range, otherwise select a smaller or larger ID.

What does the 2:1 shrink ratio mean once the tubing is on my wires?

A 2:1 ratio means the 0.750 in. inside diameter reduces to 0.375 in. after heating, and the wall thickens to 0.037 in., sealing the adhesive-lined polyolefin around the conductor.

How does the SAE-AMS-DTL 23053/4 and UL recognition limit real-world use?

The standards certify the tubing for 600 V maximum and continuous operation from -67 °F to 230 °F, with a minimum shrink temperature of 250 °F, so stay within those voltage and temperature bounds.
