Spin-on

Spin-on fuel filters are a type of fuel filter that uses a threaded housing to attach to the engine or fuel system.

The housing contains a replaceable filter element, which is designed to trap impurities such as dirt, debris, and rust particles in the fuel before they reach the engine.

The filter element is typically made of a material such as paper, mesh, or sintered metal, and is designed to trap particles down to a specific size.

To replace the filter element, the user simply unscrews the old filter from the engine or fuel system, and replaces it with a new filter by screwing it back into place.

Spin-on fuel filters are relatively simple to install and replace, and provide a good balance between filtration efficiency and cost-effectiveness.

They are often used in automotive and heavy-duty diesel applications, and are available in a range of sizes and filtration capacities to meet the needs of different engines and fuels.
