The YNF16808 O-ring, with OEM reference 6V-6228, is engineered for excavator hydraulic systems, including pumps, valves, cylinders, and connectors. Its elastomer composition—typically NBR (nitrile rubber)—offers resistance to hydraulic oil, diesel, and high-temperature fluids. Its round cross-section ensures a reliable seal even under cyclic pressure changes. It is widely stocked by spare parts dealers, workshops, and distributors catering to Caterpillar and other machinery brands.
