Heavy-Wall Tubing for Large Conductors

The 3M ITCSN-1100 is a black, adhesive-lined heat-shrink tube made from cross-linked polyolefin. Each of the twelve pieces measures nine inches long and is designed to fit wire sizes from 2 AWG up to 4/0 AWG. The material is rigid and resists abrasion, acids, alkalis and UV light. It suits installers who need a durable, water-resistant seal on heavy-gauge cables.

Sustained Thermal and Chemical Resistance

Once recovered, the tubing operates continuously from -67 degrees to 230 degrees Fahrenheit without losing its protective properties. The inner adhesive layer bonds to the conductor and jacket, creating a barrier that withstands long-term exposure to moisture, chemical splash and mechanical stress. The rigid wall maintains its shape under vibration and thermal cycling. It is not intended for applications that require a flexible or thin-wall sleeve.

3:1 Shrink Ratio and Final Dimensions

The tube shrinks from an inside diameter of 1.1 inches down to .37 inches, with a recovered wall thickness of .17 inches. This 3:1 ratio allows a single size to cover a wide range of cable diameters within the stated wire gauge window. Buyers who need a higher shrink ratio, a thinner recovered wall, or a clear tube for visual inspection should look elsewhere.

Questions about this item

Does the 3M ITCSN-1100 tubing generate heat or require power when installed permanently?

No, the 3M ITCSN-1100 is a passive heat-shrink sleeve. It only needs heat during installation, then adds no heat or power draw.

What heat source do I need to shrink the 1.1 in diameter tubing down to 0.37 in?

A standard heat gun or torch that reaches the shrink temperature will activate the 3:1 ratio and melt the adhesive liner.

Will the 0.17 in recovered wall thickness fit over my existing 2 AWG to 4/0 AWG cables without splitting?

Yes, the 3:1 shrink ratio lets the 1.1 in supplied ID slide over 2 AWG to 4/0 AWG conductors and recover to a tight 0.37 in seal.
