3M Cold Shrink Connector Insulators 8420 and 8430 Series are EPDM, factory-expanded rubber tubes designed with cold shrink technology and loaded on a removable plastic core. To install the connection, position it over the inline connector, pull the loose tab on the plastic core while unwinding the core in a counterclockwise direction, allowing the ends of the tube to shrink and form a secure seal. Engineered for primary insulation of solid dielectric insulated wires and cable splices rated up to 1000 volts,
- DESIGNED TO PERFORM: Offers reliable primary insulation for solid dielectric wires and secondary splices rated up to 1000 volts
- HIGH-RESISTANCE: Provides excellent wet electrical properties and resists fluid splashes, acids, and alkalis
- EASY TO INSTALL: Requires no tools or heating sources and can be installed by hand
- BUILT STRONG: Made of EPDM rubber, enduring operating temperatures ranging from -40 °F to 194 °F (-40 °C to 90 °C)
- MULTIPURPOSE: For environmental sealing on terminal lug barrels, conduit coupling, conduit-to-cable breakouts, and more
- WATER-RESISTANT SEAL: Meets the water-resistant requirements of ANSI C-119.1
