- The design of high pressure oil seals varies depending on the specific application
- Furthermore, the B20 series valve cover gasket helps to maintain compression within the cylinder head

ERIKS also supplies the types GR and GRST. These are virtually identical to the types R and RST, except in this case the metal inner ring is also completely encased in rubber. ERIKS uses FKM rubber here as standard, so these seals are ideal for use in acidic environments.
- 2. Clean the spark plug using a wire brush and solvent to remove any deposits that may be interfering with the spark.
In terms of size, oil seals are available in a wide range of dimensions to suit different shaft diameters and housing sizes. It is crucial to select the correct size seal to ensure a proper fit, as using an improperly sized seal can lead to leaks and premature wear.

- Regular maintenance is also crucial for the proper functioning of the piston oil seal. This includes checking for signs of wear or damage and replacing the seal as necessary. Failure to do so can result in premature seal failure and costly engine repairs.
- Proper maintenance of spark plugs is also vital. Regular checks and replacements, as recommended by the manufacturer, can ensure optimal engine performance. Worn or dirty spark plugs can lead to misfires, reduced fuel efficiency, and even engine damage. Symptoms of worn spark plugs include rough idling, difficulty starting the bike, and decreased acceleration.
How do oil seals work?
- A spark plug is a simple device with a threaded shell that fits into the cylinder head of an engine. It has a central electrode and a side electrode, separated by a small gap. When voltage from the ignition system jumps this gap, it creates a spark, which ignites the compressed fuel-air mixture inside the combustion chamber. This controlled explosion pushes the piston down, converting chemical energy into mechanical energy, driving the vehicle or appliance forward.
- A head gasket, as its name suggests, is a crucial component that seals the interface between the engine block and cylinder head. It maintains the pressure within the combustion chambers and prevents the mixing of coolant and engine oil. When a car overheats, the intense heat can cause the head gasket to fail, a situation known as a blown head gasket.

- The maintenance of oil seals is also crucial to ensure their longevity and effectiveness. Regular inspections should be performed to check for signs of wear, damage, or contamination. If any issues are detected, the seal should be replaced immediately to prevent further damage to the machinery.
The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.
- When choosing a spark plug for your vehicle, it is essential to consider the manufacturer's recommendations and the specific requirements of your engine. Factors such as the type of fuel used, engine design, and driving conditions can all affect the performance and longevity of your spark plugs. Regular maintenance and replacement of spark plugs can help maintain your engine's efficiency and prevent costly repairs in the future.
- Advancements in spark plug technology have further enhanced their utility. Iridium plugs, for instance, offer longer lifespans and improved performance due to their superior conductivity and resistance to wear. This innovation not only reduces maintenance intervals but also contributes to overall engine efficiency and vehicle longevity.
The rubber material used in the oil seal should be selected based on the operational temperature and substance to be sealed.
Table 5 lists the major rubber materials along with their operational temperature ranges.
Note that it is necessary to check the compatibility with fluids.
<N.B.>
Extreme pressure additives are compounds added to the lubricant. They are activated by heat and chemically react against rubber, which deteriorates rubber properties. For this reason, it is necessary to check for compatibility with rubber materials.


No code: without minor lip
When the bore and shaft centers are misaligned, seal life will be shortened because the wear will be concentrated on one side of the sealing lip.
