Split Cartridge Seals

Split Cartridge Seals

Flex-A-Seal offers Style 85 and Style 85M split cartridge mechanical seals. These split seals are unique in the fact that they only require two pieces to be handled for installation.

The 85M features the same great qualities as style 85 but with heavy duty capabilities. Stationary face options are carbon or silicon carbide. Elastomer options are the standard Viton, Aflas, or Fluraz. Construction is stainless steel.
