Our 3M™ connector insulator 8420 meets all your splice insulation needs because it can be used as a cold shrink insulator on all solid dielectric-insulated wires and cable splices. It also gives you excellent moisture protection for secondary splices, dig-in repairs and direct buried or submersible cable. The watertight seal it creates is durable and long-lasting to deliver a solid barrier for high voltage lines, air insulated connectors or lugs. Our 8420 connector insulator is ANSI certified and RoHS 2011/65/EU Compliant.
