Donaldson Filtration Spin-On Fuel Filter Secondary

The Donaldson Filtration Spin-On Fuel Filter Secondary is a spin-on diesel fuel filter (also called a secondary fuel filter or fuel filter cartridge). It helps protect fuel injection components from contamination in on-highway, off-highway, construction, agricultural, and industrial engines.

Key Features:

• Spin-on design for simple, tool-light service and replacement
• Secondary filtration stage that removes fine particles after the primary filter to help protect injectors and pumps
• Donaldson filtration media engineered for dependable contaminant capture and good dirt-holding capacity
• Durable steel housing and sealed construction built for heavy-duty vibration and pressure demands
• Available in multiple configurations to suit a range of engine and equipment applications

Donaldson is a long-standing filtration manufacturer, and its products are widely used as both original equipment and replacement parts in heavy-duty applications. Replacing the secondary fuel filter at the recommended service interval helps support fuel system life, engine performance, and fuel efficiency.
