Seals or gaskets are used to close gaps in fixed and moving components, reducing and preventing lubricant leakage, while also keeping harmful pollutants out of the vehicle. They are vital components for the protection of any type of machine or moving vehicle. They also help ensure consistent and reliable performance.
