3M™ Cold Shrink Connector Insulators 8420 and 8430 Series

3M Cold Shrink Connector Insulators 8420 and 8430 Series are designed using 3M’s unique 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 moisturetight seal. The live memory action of the specially formulated EPDM material promotes a permanent, durable environmental seal and insulation, with a typical operating temperature range from -40 to 90°C.

Applications

Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splicing rated to 1000 V. Good for repairs and environmental sealing for communication and other non-electrical applications

Important

Use cable insulation/jacket diameters and connector outer diameter for final sizing confirmation

For 8420 and 8430 Series Cold Shrink Tubes continuously exposed to high levels of UV radiation, 3M recommends overwrapping with Scotch®Super 33+ Vinyl Electrical Tape or Scotch®Self -Fusing Silicone Rubber Tape 70. Other sizes of cold shrink tubes are available on request.
