Make sure your connections are protected with a 3M™ 8420 Cold Shrink Connector Insulator. It guards against damage from ozone, acids and alkalis, and it provides primary electrical insulation for applications rated up to 1 kV. Its EPDM rubber construction provides rugged environmental sealing and makes it suitable for operating temperatures ranging from -40 to 194 degrees F (-40 to 90 degrees C).

  • Specially designed for primary insulation of solid dielectric insulated wires and cable splicing rated to 1000 volts
  • Simple installation which requires no tools
  • Sealing of terminal lug barrels, conduit couplings and conduit-to-cable breakouts
  • Made of black EPDM rubber
  • Made of EPDM rubber which contains no chlorides or sulfur
  • Withstands temperatures of -40 to 194 degrees F (-40 to 90 degrees C)
  • Environmental sealing for communication and other non-electrical applications

You can count on the 3M™ 8420 Cold Shrink Connector Insulator to seal out moisture on all solid dielectric insulated wires, cables splices, conduit sealing and breakouts. The cold shrink bond maintains pressure and stays flexible, making it a great choice for insulating secondary splices, direct buried or submersible, dig-in repairs, as well as safeguarding high-voltage, air-insulated connectors and lugs. It needs no tools to install, and it's made of EPDM rubber that contains no sulfur or chlorides. This insulator is ANSI Certified and RoHS 2011/65/EU Compliant.   Add to cart
