No. - Overall, the m20 valve cover gasket plays a vital role in the proper functioning of your vehicle's engine. Regular maintenance and replacement of the gasket as needed can help to prevent costly repairs and keep your engine running smoothly for years to come.
Single - Metric oil seals are an essential component in machinery and equipment to prevent leakage of oil and other liquids. These seals are commonly used in automotive, aerospace, industrial, and manufacturing applications to ensure smooth and efficient operations.
MHA Both sealing types are popularly used in different mechanical engineering applications. How are they different? The article explains the fundamental working mechanism of both categories of seals.
- In the automotive industry, square rubber gaskets are crucial in engine compartments, sealing oil pans, valve covers, and other components. They prevent oil leaks and maintain the optimal functioning of the engine. Similarly, in plumbing, they ensure leak-proof connections between pipes, taps, and fittings, safeguarding against water damage and potential disasters.

- Moreover, silicone rubber gasket sheets are known for their durability and long service life. Their inherent elasticity allows them to withstand compression set, meaning they can maintain their original shape even after prolonged use. This property is particularly beneficial in applications where constant pressure is applied, such as pipe connections and machinery seals.
The sealing lip is always made of a rubber or synthetic material. For oil seals with a rubber outer case (R, RST, GR, GRST), the rubber quality of the sealing lip and the outer case are the same.

Even the slightest chip or dent can cause contaminants to infiltrate your oil seal. If there are any scratches on the shaft, a leak path may develop, allowing the lubricant to drip. To protect the shaft from damage, wrap it in a mesh rubber screen and store it vertically in its compartment. This way, it can be shielded from potential cracking.
Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.


When it involves a repair, you must first remove the old oil seal. To remove an oil seal, it is important to use the right tools to avoid damaging the shaft and bore. The best solution is therefore to pull out the oil seal without having to completely dismantle the shaft. This can be done by making a few holes in the oil seal with an awl and a hammer. You can then use a hook to pull the oil seal out of its seat. You could also screw some screws into the holes and then slowly pull out the screws to extract the oil seal from its housing. Be careful not to damage the shaft or housing in the process.
In order to use the oil seal reasonably, the following points should be paid attention to:
