No, there are generally no universal replacement parts for different brands of air tools. Air tools are designed and manufactured by various companies, each with its own specifications, designs, and engineering standards. As a result, parts such as motors, valves, seals, and other components are typically brand-specific and often model-specific. 
While some generic parts like hoses, connectors, and fittings may be interchangeable due to standardized sizes (e.g., NPT threads for connectors), critical internal components are usually not interchangeable between different brands or even different models from the same brand. This is because each manufacturer may use proprietary designs, materials, and dimensions that are unique to their products.
Additionally, using non-specific parts can lead to performance issues, reduced efficiency, or even damage to the tool. It can also void warranties and affect the safety of the tool's operation. Therefore, it is recommended to use original equipment manufacturer (OEM) parts or those specifically designed for the particular brand and model of the air tool.
In some cases, third-party manufacturers may produce compatible parts for popular models, but these should be used with caution and verified for compatibility. Always consult the tool's manual or contact the manufacturer for guidance on replacement parts to ensure proper fit and function.
