- Overall, a thin rubber gasket may be a small component, but its importance should not be underestimated. It plays a critical role in sealing applications across various industries, ensuring the safe and efficient operation of equipment. By choosing high-quality gaskets and designing them to meet specific requirements, manufacturers can improve the performance and longevity of their products.
Operating conditions such as the engine’s temperature, position, size, pressure and shaft speed largely determine which individual oil seal composition is most suitable for every individual application.
Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.
- At its core, a spark plug motor integrates the spark plug directly into the motor's design, aiming to optimize combustion and enhance electrical generation. The integration ensures that the energy produced during the combustion process is harnessed more effectively, reducing waste and improving fuel economy. This synergistic relationship between the spark plug and the motor not only results in increased efficiency but also reduces the overall weight of the engine components, contributing to improved vehicle dynamics and reduced emissions.
Place the ruler or straight-edge on edge diagonally across the head and block and look for gaps showing light anywhere between the ruler and block.

After the oil seal is positioned in the groove, apply even pressure to the oil seal using a seal driver or a similar tool. This will help to seat the oil seal firmly in the groove and prevent it from moving during use. Make sure to apply the pressure evenly and gently, as applying too much force can damage the oil seal or cause it to deform.
3. Seal types and numbering system

There are different types of spark plugs available on the market, each designed for specific engine types and operating conditions. The most common types are copper, platinum, and iridium spark plugs. Copper spark plugs are the most affordable and provide good performance for everyday driving. Platinum spark plugs offer better longevity and performance, while iridium spark plugs are the most durable and provide the best spark performance.

ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.
Oil seal type or shape
Entry of dust and debris is one of the most common reasons oil seals fail. For instance, in high-pressure applications, even the smallest sediments can create a gap in the seal, causing the oil to leak and dirt to get in.
