3M's 8420, 8430 and 8440 Series Splice Kits are cold shrink splicing products using 3M's unique cold shrink delivery system. The products are supplied as pre-stretched tubes on a removable core for efficiency and ease of installation. The tubes are open-ended, rubber sleeves, which are factory expanded and assembled onto removable plastic cores. The removable core is unwound after positioning the splice, allowing the tube to shrink into position and form a moisture resistant seal. The live memory action of the specially formulated material ensures a permanent, durable environmental seal and insulation.

3M's 8420 and 8430 Series insulators are made from EPDM rubber. 3M's 8440 Series Silicone Insulators are made from specially formulated high-temperature silicone rubber.
