3M ITCSN-1500-9 Heat Shrink Tubing 1.5in ID Black 9in PK3

SKU CH-2M3N-7WG9V

Heat-shrink tubing with adhesive lining shrinks from 1.5 in to .5 in ID at 250 °F, resisting abrasion, chemicals and UV from -67 °F to 230 °F

  • Product typeEnclosures
  • Color and finishBlack
  • Heavy-wall protection from 3:1 shrink ratio
  • Adhesive lining seals out moisture and contaminants
  • Abrasion- and chemical-resistant cross-linked polyolefin
  • UV-stable black finish endures outdoor exposure
  • Operates reliably from -67 °F to 230 °F

Heavy-Wall Tubing for Large-Cable Sealing

This heat-shrink tubing fits wire sizes from 3/0 AWG to 400 MCM and shrinks from a 1.5 in. inside diameter down to .5 in. The cross-linked polyolefin wall is lined with adhesive that flows during shrinking to create a watertight seal. Each pack contains three 9 in. pieces ready for individual use.

Sustained Environmental Resistance

The material resists abrasion, acids, alkalis and UV light across a continuous temperature range of -67 to 230 degrees F. Adhesive bonding remains stable during long-term exposure to vibration and thermal cycling. A minimum shrink temperature of 250 degrees F ensures reliable activation with standard heat tools.

Rigid Construction with Adhesive Lining

After shrinking the wall thickness measures .17 in., providing rigid mechanical protection for heavy conductors. The adhesive liner fills surface irregularities on the cable jacket to block moisture ingress. Black finish matches common automotive and industrial harness colour codes.

Questions about this item

How much heat does the 3M ITCSN-1500-9 tubing need to reach its minimum shrink temperature of 250 degrees F?

A heat gun or torch capable of 250 degrees F is required; the tubing itself generates no heat during operation.

What wire sizes must I already have for the 1.5 in ID tubing to fit before shrinking?

The tubing fits 3/0 AWG to 400 MCM conductors before shrinking down to 0.5 in ID.

Will the 3:1 shrink ratio and 0.17 in recovered wall work over my existing 400 MCM cable insulation?

Yes, the 3:1 ratio reduces 1.5 in to 0.5 in, leaving a 0.17 in adhesive-lined wall that seals over large-gauge insulation.
