No, there are no universal nozzles that fit all desoldering tools. Desoldering tools, which are used to remove solder from electronic components, come in various designs and sizes, and each tool may have its own specific nozzle requirements. The compatibility of nozzles depends on several factors, including the brand, model, and type of desoldering tool. 
Different manufacturers design their desoldering tools with proprietary nozzle fittings to ensure optimal performance and to encourage the use of their own accessories. As a result, nozzles are often not interchangeable between different brands or even between different models from the same brand. 
Additionally, desoldering tools can vary in terms of their heating elements, suction mechanisms, and intended applications, which further influences the design and compatibility of the nozzles. For instance, some nozzles are designed for high-temperature applications, while others are meant for precision work on small components. 
To ensure compatibility, it is important to refer to the manufacturer's specifications and recommendations when selecting nozzles for a desoldering tool. Some manufacturers may offer a range of nozzle sizes and shapes that are compatible with their tools, but these are typically specific to their product lines. 
In summary, while there may be some nozzles that fit multiple models within a single brand, there is no truly universal nozzle that fits all desoldering tools across different brands and models.
