Donaldson Fuel Spin-Ons

Fuel spin-ons are fuel filters in a spin-on format, threading directly onto a mounting head so that the complete filter is replaced as one sealed unit. That makes them quick to change and reduces the chance of introducing dirt during servicing, which matters on a fuel system.

Some spin-on fuel filters are purely particulate filters and others incorporate water separation with a drain at the base; the two are not interchangeable if the application depends on water removal. Thread size, gasket dimensions and sealing face all have to match the head. Search by Donaldson part number, or enter the number from the filter currently fitted.
