Protect your work from ozone exposure, acid leaks and alkalis with the 3M Cold Shrink Connector Insulator 8420 series. Its open-ended, tube-shaped design and 1 kV rating has the sleeve to act as both a moisture barrier and insulator in primary electrical applications. Made from strong, EPDM rubber, the black insulator stands up to an expansive temperature range of -40 to 194 degrees F (-40 to 90 degrees C).

  • DESIGNED FOR PRIMARY INSULATION: For use with solid dielectric insulated wires and cable splicing rated to 1000 volts
  • QUICK, EASY INSTALLATION: Simple installation which requires no tools
  • SEALS TIGHT: Retains its resiliency and pressure even after prolonged years of aging and exposure
  • TOUGH EPDM RUBBER FORMULATION: Withstands backfilling, for indoor and outdoor use, direct burial and submersible
  • TEMPERATURE RANGE: Withstands temperatures of -40 to 194 °F (-40 to 90 °C)
  • WATER-RESISTANT: Meets the water seal requirements of ANSI C119.1
