Oil Filters

Oil Filters

We build NAPA Heavy-Duty Oil Filters to take on specific challenges in marine environments. For example, we design the inner element of our heavy-duty oil filters to ensure system integrity by withstanding wide fluctuations in flow and high differential pressure.

Air Filters

Among many other performance features, some NAPA Heavy-Duty Air Filters for marine applications have silicone gaskets permanently bonded to end caps to eliminate any possibility of air bypass. They stay sealed under all temperatures, are impervious to environmental conditions, do not take a compression set, and seal by deflection, not distortion.

Fuel Filters

Fuel Filters

NAPA Heavy-Duty marine filtration solutions include fuel filters with application-specific features. For example, our double-lock seam secures the can and cover plate assembly. We also use a sealing compound to ensure a leak-free seal, and use spot welds to join the base plate and cover plate.
