The Donaldson P550425 is a spin-on bypass oil filter. Unlike a standard full-flow filter, a bypass filter cleans a small portion of oil at a very fine level (down to 5-21 microns) to trap microscopic contaminants that can cause premature engine wear.

It is typically used in heavy-duty diesel engines to extend oil life and better protect critical components like bearings and camshafts.
