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 Features: 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
