- In addition to the cost of the spark plugs, it's also important to consider the lifespan of the spark plugs you choose. Some spark plugs may need to be replaced more frequently than others, which can impact the overall cost of maintenance for your vehicle. Investing in long-lasting spark plugs may save you money in the long term by reducing the frequency of replacements.
Finding oil spots under a parked vehicle can be both worrying and stressful for any vehicle owner. If the seal’s leak is small, oil may start to accumulate on the underside of the engine. But as the leak gets bigger, the oil leak will become visible in the front side of the engine.

Overall, the 40mm rubber gasket is a versatile and reliable sealing solution that is widely used in various industries for different applications. Its ability to provide a tight seal, resist high temperatures and pressure, and dampen vibrations makes it a valuable component in ensuring the efficiency and reliability of industrial equipment and machinery. Whether in plumbing systems, automotive engines, or hydraulic systems, the 40mm rubber gasket plays a crucial role in maintaining operational efficiency and preventing costly leaks or contamination.
(5) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.
Storage and Handling
Oil seal WG1087811 is used by several automotive manufacturers, such as Opel, Fiat and Suzuki, and serves as a good example for an oil seal where oil leakage can occur if fitted incorrectly.
Polytetrafluoroethylene
Chemical resistant
Low coefficient of friction poor elastic properties not wear resistant if used by dynamic applications
Valve cover gaskets and head gaskets are essential components in automotive engines, serving distinct yet crucial roles in maintaining the integrity and functionality of the engine. The valve cover gasket seals the junction between the valve cover and the cylinder head, preventing oil leaks and contaminants from entering the engine. On the other hand, the head gasket seals the cylinder head to the engine block, ensuring the containment of combustion gases and the separation of oil and coolant passages.
