Cold Shrink Low Voltage Insulators
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 moisture-tight 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.
Important: Use cable insulation/jacket diameters and connector outer diameter for final sizing confirmation
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

*These sizes are not designed to be used as primary insulation.These shorter length tubes are for conduit sealing and breakouts.
**8424-8 contains range-extending adapters (without adapters, 8424–8 and 8425–8 products are identical).
Note: Insulation, connector and/or jacket can be overwrapped with Scotch® Rubber Mastic Tape 2228 to build up diameter if required.
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. See pages 2 and 5.
Other sizes of cold shrink tubes are available on request - please contact 3M.
