In terms of safety, SC oil seals play an essential role. Lubricants that are not contained properly can pose slip hazards on walkways or create fire risks if they come into contact with hot machinery components. Properly functioning oil seals eliminate these risks, ensuring a safer work environment for employees.NBR rubber is above all resistant to oils, especially hydraulic oils, lubricants, petrol and other aliphatic hydrocarbons, diluted acids and lyes. Good physical values such as high friction resistance and ruggedness and good temperature resistance (-25 °C up to +120 °C, in part to -40 °C) give this natural rubber a wide range of uses.

An auto gasket, a seemingly insignificant component, plays an essential role in the overall functionality and performance of a vehicle. A gasket is a thin, usually ring-shaped seal that is designed to fill the space between two or more mating surfaces, preventing leakage from or into the joined components. In automotive engineering, gaskets are vital for maintaining the integrity of various systems, including the engine, transmission, and cooling system.

Over time, engine oil seals can become worn or damaged due to normal wear and tear or exposure to extreme temperatures and chemicals. When this happens, they may need to be replaced to prevent further damage to the engine. It is recommended to have the oil seal checked and replaced at regular intervals, typically every 30,000 to 100,000 miles, depending on the make and model of the vehicle.
