Five black heavy-wall heat-shrink tubes, 48 inches each, adhesive lined, 3:1 shrink ratio

3M

3M ITCSN-0400 Heat Shrink Tube 48" Black 5 PCS Adhesive Lined 3:1

SKU CH-9P0Q-GSE54

Adhesive-lined heavy-wall polyolefin tubing shrinks 3:1 to seal 12 AWG to 6 AWG wires, resisting abrasion, chemicals and UV from -67 to 230 °F

  • Heavy-wall protection for 12–6 AWG wires
  • 3:1 shrink ratio seals connections from .4 in to .15 in
  • Adhesive lining bonds and waterproofs after heating
  • Cross-linked polyolefin resists abrasion, chemicals and UV
  • Withstands temperatures from -67 °F to 230 °F

Heavy-wall adhesive-lined heat-shrink tubing

3M ITCSN-0400 tubing is a heavy-wall, adhesive-lined polyolefin sleeve with a 3:1 shrink ratio. Each piece measures 48 inches long and is supplied in a pack of five. The material is abrasion-resistant, acid- and alkali-resistant, and UV-light-resistant for harsh environments.

Suited for 12 to 6 AWG wire sealing and protection

This tubing fits wires from 12 AWG to 6 AWG, sealing connections against moisture and mechanical stress. The rigid, adhesive-lined wall creates a durable environmental seal after shrinking. It is not intended for users who need a higher shrink ratio or a flame-retardant rating for regulatory compliance.

Verify wire gauge and operating temperature range

Confirm your conductors fall within the 12 to 6 AWG range so the .4 inch inner diameter shrinks to a secure .15 inch fit. The wall thickness after shrinking is .09 inch. Ensure the -67 to 230 degrees F temperature range covers your application before ordering.

Questions about this item

What wire gauges does the 3M ITCSN-0400 tube cover?

The tube is rated for wire sizes from 12 AWG to 6 AWG, matching the 3:1 shrink ratio and the 0.4 in inner diameter before shrinking.

Will the adhesive bond to older cross-linked polyolefin insulation already in the harness?

The adhesive lining is designed to bond to polyolefin and common wire jackets, creating a moisture-resistant seal when heated to the 230 °F upper limit.

How can I confirm the 0.15 in recovered diameter and 0.09 in wall thickness after shrinking?

After applying heat, measure the cooled tube with calipers; the inner diameter should read 0.15 in and the wall 0.09 in if shrinkage is complete.
