Banjo Sealing Washers

Banjo Seals are specifically designed to meet the demands of high-pressure applications, particularly in the automotive and heavy-duty vehicle sectors. They offer a high-performance alternative to traditional copper or aluminum washers.
Thanks to the elasticity of the rubber material, these rings ensure reliable and long-lasting sealing, even in the most challenging environments. Their design includes a self-centering lip that simplifies assembly, reducing the risk of installation errors and enhancing overall assembly efficiency.

Main Benefits
  • Tailor-made solutions: design of parts and compounds formulations

  • Easy fitting thanks to self-centering

  • Improve sealing capacity thanks to rubber lip
