Detailed Description

This Elring vacuum pump gasket is a direct-fit sealing component for select Mercedes-Benz C250, C300, GLK300, E350, SLK300, C230, CLK280, E300, GLK280, E280, SLK280, and C280 applications. It is engineered as an O-ring style seal and is sized to match the listed vacuum pump interface dimensions, helping maintain a tight seal at the pump mounting point. If you are replacing a leaking vacuum pump seal on a Mercedes-Benz C300 or E350, Elring 284.330 provides the correct dimensional match for the specified applications.

What This Part Helps Address

  • Vacuum pump oil seepage at the sealing surface
  • Loss of vacuum caused by a worn or flattened gasket
  • Engine bay leaks around the pump mounting area
  • Seal deterioration from heat and fluid exposure
  • Repeat leakage after vacuum pump service when the old seal is reused

Installation Notes and Tips

Verify the gasket dimensions against the removed seal before installation. Clean the mating surfaces thoroughly so the O-ring seats evenly, and inspect the vacuum pump flange for damage, scoring, or contamination.
