A dome cover gasket for oils and corrosive substances is a specialized seal installed between the dome cover and the tank to ensure chemical-resistant and secure sealing. It is typically made of high-quality materials such as FKM (Viton®), PTFE (Teflon®), or EPDM, depending on the application. These gaskets are resistant to aggressive media such as mineral oils, acids, alkalis, and solvents. They prevent hazardous substances from leaking and protect both the environment and personnel.
