3MÂ™ Cold Shrink Connector Insulators 8420 and 8430 Series are designed using 3MÂ’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 -40Â–194Â°F (-40Â–90Â°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 usedas primary insulation. These tubes are for conduit sealing and breakouts. ****Maximum connector length: 5.625Point of Purchase packaging designated by P. Example: 8423-6P

Cold Shrink Connector Insulators
3M™ 054007-42147 8420 1-Conductor Cold Shrink Connector Insulator, 1.68 in Min Dia, 3.69 in Dia, 9 in L, 1400 psi Tensile, Aluminum/Copper/EPDM Rubber
3M™ cold shrink insulators are open ended, tubular, EPDM rubber sleeves which are factory expanded and assembled onto a removable core. The core is removed after the tube has been positioned for installation over an in-line connection, terminal lug, etc, allowing the tube to shrink and form a water-resistant seal. 3M™ cold shrink insulators are designed using a unique cold shrink delivery system. They are supplied pre-stretched on a removable core for efficiency and ease of installation. Removal of the core after positioning allows the product to shrink into position forming a moisture tight seal. The live memory action of the specially formulated material ensures a permanent, durable environmental seal and insulation.
