What's the Difference Between a Gasket and a Seal?

Typically seals are used for dynamic components (flange) between pumps, engine parts, shafts and related applications. Seals are typically used when shafts rotate rather than those that are static. Gaskets seals a connection between 2 flat surfaces that are typically static.

OneMonroe offers many guides on seals & gaskets including: Comparison Properties Chart, Fluid Compatibility Tables, Gasket Materials, Oil Seal Material Design Guide & Spring Energized Seal Guide.
