4:1 Polyolefin Heat Shrink Tubing

Available In 1/2" - 1-1/2" Inside Diameter - 4 Ft Sticks & Bulk Rolls

4:1 Heat Shrink Features

  • Please Note: Our Diameters for Heat Shrink Tubing are measured as ROUND TUBE, NOT FLAT.
  • Shrink ratio: 75% or more in the radial direction, 50% or less in the axial direction
  • Continuous operating temperature: -55°C (-67°F) to 135°C (275°F)
  • Flammability: UL VW-1, CSA OFT (except clear)
  • High resistance to abrasion, chemicals and oils


Kable Kontrol® 4:1 over-expanded polyolefin heat shrink tubing is flexible, flame-retardant, and used for specialty applications that include cable jacket retrofitting and repair, as well as the electrical insulation of wire assemblies with oversize components or connectors. The over-expanded product fits easily over the end of a connector and shrinks down to 25% of its original diameter to fit snugly over both the connector and any narrower attached wires. Available in Black.
