No 2 Electrical Joint Compound
No 2 Electrical Joint Compound

No. 2 Electrical Joint Compound


  • Lowest electrical resistance on flat surfaces
  • Grease-type medium dissolves the oxide on connectors
  • Adheres to pad surfaces, protecting the connection against the harmful effects of the environment
  • Proven results in laboratory testing and years in service for efficient and trouble-free service


  • Terminal to dead end connections for applications under 93ºC (200ºF)
  • Flat-to-flat surfaces such as bus-t- bus, aluminum-to-aluminum and aluminum-to-copper

Product Description

AFL's No. 2 Electrical Joint Compound (EJC) is the recommended compound providing efficient and trouble-free service on aluminum-to-aluminum and aluminum-to-copper connections. If No. 2 EJC is kept in a dry place, it has an infinite shelf life.

No. 2 EJC has the lowest electrical reistance on flat surfaces because it is a grease type medium that dissolves the oxide on connectors. The nature of the oxide removal is not harmful. Unlike other compounds of its kind, No. 2 EJC creates a light surface etch with no deep, localized attack.
