3M Cold Shrink Tubing, Black 35mm Sleeve Dia. x 305mm Length, 8420 Series - 8427-12

3M Rubber Cold Shrink Connector InsulatorThe 3M 8420 series black 305mm cold shrink connector insulator is an open-ended, tubular, rubber sleeve. It is factory expanded and assembled onto a removable core. The core is removed after the tube is positioned for installation over an inline connection and terminal lug. This allows the tube to shrink and form a water-resistant seal. The insulating tube is made of EPDM rubber which does not contain chlorides or sulfur. It is available in diameter sizes that cover a range of cable up to 1000V for copper and aluminium conductors.Features and Benefits• Conductor size range between 250kcmil and 400kcmil • Sleeve diameter is 35.1mm • Shrunk diameter 16.8mm • Excellent wet electrical properties • Good thermal stability • Improved, tougher rubber formulation to withstand backfilling • No mastic or tape required to seal • No torches or heat required • Resists acids and alkalis, resists ozone Seals tight, retains its resiliency and pressure even after prolonged years• of aging and exposure • Physical protection and moisture sealing for high voltage, air-insulated connectors and lugs such as spacer cable and lug connections to bus bar • Simple installation, requires no tools • Directly buriable or submersible • Thick-walled to resist puncture and damage • Water-resistant • Operating temperature ranging between -40°C and 90°CApplications• Dig-in repairs • Direct burial or submersible.
