Atlas Copco washer part number 0339100002 is a genuine original sealing and auxiliary fastening component specifically designed for the GA series screw air compressors. It precisely fits key scenarios such as pipeline interfaces, flange connections, and component assembly of GA models, often used in conjunction with bolts and nuts. As a core protective element for the connection points of GA models, this washer primarily serves three core functions: First, it forms a sealing barrier at the interfaces of fluid transmission pipelines (such as lubricating oil pipes and cooling water pipes). Through the elastic deformation of its material, it fills interface gaps to prevent oil and coolant leakage while blocking external dust and moisture from entering the pipelines, ensuring the sealing integrity and cleanliness of the GA model's fluid system. Second, in component assembly connections, it increases the contact area between the bolt and the connected part, distributing the fastening force evenly across the component surface to avoid deformation or damage to thin-walled parts like casings and panels caused by excessive local pressure. Third, it reduces direct friction between the bolt head and the connected part, preventing the bolt from adhering to the component due to rust, thereby facilitating disassembly during subsequent equipment maintenance and reducing maintenance difficulty.
As a genuine original part, the production of this washer strictly adheres to Atlas Copco's high-standard quality system. It is made from oil-resistant and aging-resistant rubber or metal materials through precision processing, offering excellent elastic recovery and corrosion resistance. It can adapt to complex operating conditions such as temperature fluctuations and fluid erosion during the long-term operation of GA models, avoiding sealing failure or structural damage caused by material degradation. Its dimensional parameters, including inner diameter, outer diameter, and thickness, fully match the corresponding bolt specifications and installation interfaces of GA models. It can precisely fit onto the bolt shank and form a tight connection with the components, allowing direct assembly without additional adjustments and ensuring that the sealing and fastening effects meet the original design standards. Through pre-delivery sealing tests, dimensional accuracy inspections, and durability verifications, this washer provides reliable protection for various connection points of the GA series air compressors, helping to maintain stable equipment operation, reduce failures caused by leaks or connection issues, extend component service life, and ensure long-term efficient operation of the entire machine.
