Made for off-road equipment performance
In today’s nonstop working environment, we know you demand more from your heavy-duty, off-highway vehicles and equipment. So we demand more from the NAPA Heavy-Duty Air Filters you depend on to protect them.
In addition to adding many other design features, we use pleating and embossing to strengthen our heavy-duty air filter media pleats. Our specially plated, corrosion-resistant metal end caps are bonded to the filter media, and our rubber-backed sealing washer ensures thread seal distribution of torque from the wing nut.
Some of our air filters 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. Other NAPA Heavy-Duty Air Filters have foam gaskets that use a concentric mold and superior end cap adhesion, eliminating the possibility of air bypass.
