The quick connector/adaptor used for a tornador cleaning gun, such as a Tornador or similar models, typically depends on the air hose and compressor setup you have. Here are a few common types of quick connectors that might be used:

1. Standard Quick Connectors: These are often used in pneumatic tools and equipment. They come in various sizes (commonly 1/4 inch or 3/8 inch) and are compatible with most air hoses and compressors.

2. Universal Couplers: These connectors feature a push-to-connect mechanism, making them easy to attach and detach from air hoses and tools quickly.

3. Industrial Interchange Couplers: These are heavy-duty connectors suitable for high-flow applications. They often have a ball-bearing locking mechanism for secure connections.

4. European, Japanese, or US Style Couplers: Depending on the origin of your cleaning gun or air compressor, you might encounter specific regional styles of couplers. These are designed to match corresponding fittings commonly used in different parts of the world.

When selecting a quick connector/adaptor for your cleaning gun, ensure compatibility with both the air hose and the compressor's fittings. It's essential to use fittings that match in size and style to prevent air leaks and ensure efficient operation of your cleaning gun. If you're unsure about the type of quick connector to use, consulting with the manufacturer's recommendations or seeking advice from a supplier specializing in pneumatic equipment can provide clarity and ensure you choose the correct connector for your setup.
