3M ITCSN 1100 Heavy Wall Adhesive Heat Shrink Tube 48 in Black 3:1

SKU CH-9A5Y-RHV85

Heavy-wall adhesive-lined heat-shrink tubing with a 3:1 shrink ratio, covering 2 AWG to 4/0 AWG, shrinking from 1.1 in to .37 in with a .12 in recovered wall, 48 in long, rated from -67 °F to 230 °F

  • Heavy-wall insulation seals out moisture with adhesive-lined cross-linked polyolefin
  • 3:1 shrink ratio covers 2 AWG to 4/0 AWG wire sizes reliably
  • Abrasion, acid, alkali and UV resistance protects cables in harsh environments
  • Operating range from -67 °F to 230 °F suits extreme temperature conditions
  • Four-foot black lengths with 1.1 in ID shrink to 0.37 in for secure fit

Heavy-Wall Heat-Shrink Tube 48 in

This 3M ITCSN 1100 tube is a cross-linked polyolefin sleeve with an inner adhesive liner. It suits electricians and technicians who need environmental sealing on cables from 2 AWG to 4/0 AWG. The rigid construction resists abrasion, acids, alkalis and UV exposure. Each piece is 4 ft long and ships as individual units.

3:1 Shrink Ratio and Temperature Limits

The tubing shrinks from a 1.1 in inner diameter down to .37 in, recovering a .12 in wall thickness. This 3:1 ratio only works when the cable diameter falls within the stated AWG range. Continuous operation is rated from -67 Degrees to 230 Degrees F; exceeding either limit can compromise the seal or the material integrity.

Installation Notes and Common Issues

A heat gun with even airflow is required to activate the adhesive and achieve full recovery. Uneven heating leaves voids in the liner and reduces mechanical protection. The rigid wall makes positioning stiff on large conductors, so align the tube before applying heat. Insufficient shrink temperature is the most frequent cause of field failures.

Questions about this item

How do I choose between the available lengths for the ITCSN 1100 heavy-wall tubing?

This listing supplies 48-inch individual pieces; each piece covers a 4 ft run and shrinks from 1.1 in to 0.37 in ID with a 0.12 in wall.

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

The 1.1 in inner diameter reduces to 0.37 in, and the adhesive-lined wall thickens to 0.12 in, sealing 2 AWG to 4/0 AWG conductors.

What temperature range does the cross-linked polyolefin withstand in service?

The material is rated from -67 °F to 230 °F and resists abrasion, acids, alkalis and UV exposure.
