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.

3M™ Connector Insulator, Cold Shrink, Series: 8420, 49.2 mm Minimum Dia, 24.1 mm Maximum Dia, 1400 PSI Tensile, 7.5 Elongation, 365 V/mil Dielectric, EPDM Rubber Insulation, Black
