The corrosion-resistant EPDM rubber O-ring series products are available in various materials such as fluororubber, nitrile rubber, and silicone rubber, and are widely used in various mechanical equipment. They are resistant to various crude oil-based oils and various organic chemicals. The application temperature range for different rubber types can reach -60℃ to +300℃, and the application pressure range is less than 10MPa (hydraulic), less than 1MPa (pneumatic), and less than 16MPa (packed seal). The expansion coefficient of nitrile rubber and gasoline-resistant rubber (90, 93, 97) is 0.
