WEGMANN automotive battery bushings stand for highest quality. All well-known battery manufacturers trust in our products. Our product portfolio is based on deep market knowledge and close partnerships with our customers to guarantee the best product for the application purpose.

 

Special surface treatment

In order to provide a shiny appearance and an improved surface finish, our battery terminals are surface treated over the entire cone area.

Advanced undercut labyrinth

For an optimal connection between the battery bushing and the polypropylene of the battery lid we developed the advanced undercut labyrinth. This unique feature prevents acid migration through the labyrinth and helps to make the battery leakageproof.

  • Highest precision for superior profile
  • Optimal connection between synthetic material and terminal
  • Labyrinth shape enables best possible sealing
