Oil seals with a 30% ratio are considered to be high-performance seals, capable of handling extreme pressure and movement. These seals are commonly used in heavy-duty machinery and equipment that operate under demanding conditions. With a 30% oil seal ratio, these seals offer superior fluid containment and durability, making them ideal for applications where there is a high level of stress on the seal. They are designed to withstand intense operating conditions, ensuring that oil and other fluids stay securely contained within the system
