Rely on tested quality and order sealing rings & O-rings for your engine online.

Sealing under load

Sealing rings (e.g., shaft seals, O-rings) ensure that oil, fuel, or coolant do not leak out and that no foreign substances can enter. They secure critical joints—such as those at shafts, flanges, or covers—and play a key role in maintaining the integrity of the engine and its systems.

Technology that keeps tight

For a seal to function reliably over the long term, the material, cross-section, and compression mechanism must be selected correctly. The annular design must be tailored to the sealing surface to ensure lasting elasticity. Key factors include compatibility with lubricants, temperature ranges, and pressure levels.

Sealing Ring

What should you look out for when buying:

CONSTRUCTION

The inside diameter, outside diameter and cross-section (e.g. round, square profile) must match the shaft or flange geometry exactly.

MEDIA COMPATIBILITY

Select a material (e.g. NBR, FKM, Viton) that is resistant to oil, fuel, coolants or additives in the long term.

PRESSURE RESISTANCE

The sealing ring should be designed to withstand the temperature and pressure conditions encountered in the engine without losing its elasticity.

Optimize your engine sealing in the long term!

With the right sealing rings, you can protect sensitive components from leaks and ensure reliable engine operation even under heavy loads. Choose the right components in tested quality for a perfect seal.
