Features
1 piece
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
3M Cold Shrink Connector Insulators 8420 and 8430 Series are designed using 3M’s proprietary cold shrink delivery system. Products are supplied prestretched on a removable core for efficiency and ease of installation. Removal of the core (unwinding) after positioning the splice allows the product to shrink into position forming a moisture-tight seal. The live memory action of the specially formulated EPDM material promotes a permanent, durable environmental seal and insulation, with a typical operating temperature range from -40–194°F (-40–90°C). The 8420 insulator meets requirements of ANSI C119-1 and Western Underground Guide 2.14 for secondary splices rated up to 1 kV. Applications: Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splicing rated to 1000 V. Good for repairs and environmental sealing for communication and other non-electrical applications. Important: Use insulation jacket or connector O.D. for final ordering criteria. * Mastic pads included for cable O.D. build-up. ** Kit contains adapters. *** These sizes are listed for availability only and are not designed to be used as primary insulation. These tubes are for conduit sealing and breakouts. ****Maximum connector length: 5.625” “Point of Purchase” packaging designated by “P”. Example: 8423-6P
3M 8420 Connector Insulator is designed for use on all solid dielectric insulated wires and cable splices. This cold shrink insulator offers moisture tight sealing while maintaining its prolonged resiliency and pressure. It is ideal for insulating secondary splices, direct buried or submersible, dig in repairs and physical protection of high voltage, air insulated connectors or lugs. ANSI Certified and RoHS 2011/65/EU Compliant.
