3MÂ™ 8440 Series Cold Shrink Silicone Insulator is an insulating sleeve that is specially formulated from high temperature silicone rubber for moisture protection. It maintains resiliency and pressure, even after years of aging and exposure. This insulator ensures top moisture sealing for medium voltage, air insulated connectors and lugs. It offers resistance against acids, alkalis, fluid splashes, ozone, ultraviolet light and fire. This insulator is ideal for use in sheath repairs and electrical aircraft cables and it provides insulation for inline conductor transition connectors. RoHS 2011/65/EU Compliant.

Silicone Cold Shrink Connector
3M™ 8443-2 8440 Splice Cold Shrink Insulator, 0.3 in Min Dia, 0.56 in Dia, 1.4 in L, 1240 psi Tensile, Silicon
3M™ Cold Shrink Connector Insulators 8440 Series are open-ended, silicone rubber, tubular sleeves. The sleeves are factory expanded and assembled on a removable supporting plastic core. Each rubber assembly is supplied for field installation in this pre-stretched condition. As the core is unwound, the insulating sleeve shrinks to form a tight seal. Three sizes of Cold Shrink Insulators cover terminal lug barrels and inline connectors.
