Internal Combustion Engines

In 1960 FEY developed the FK5-HFL sealing ring designed to handle the demands of sealing exhaust gases in internal combustion engines. Sealing exhaust gases require the sealing solution to deal with,

  • Very High Operating Temperatures
  • High Axial and Radial Movement
  • Misalignment
  • High Pressure

Over the years the sealing requirements of internal combustion engines have evolved. The current features of FK5-HFL Sealing Rings reflect these changes and FEY’s design experience.

Engine Applications

There are many applications where successful sealing solutions are in operation. These include,

  • Exhaust Manifold Joints
  • EGR Joints
  • EGR Flaps
  • Axial Compensators
  • Turbochargers
  • Air control Valves
