WHY THIS FILTER
● Axial seal inner (safety) air element — the inner element is the final barrier protecting the engine if the outer primary filter is damaged or improperly installed. Never run heavy equipment without it.
● Axial seal with metal end caps & raised gasket — securely affixed metal end caps with a raised sealing gasket eliminate the bypass leaks common in lesser inner elements, ensuring a positive, reliable seal every service.
● Fits inside 5 confirmed outer elements — compatible with LL1902-FN, PA1902-FN, PA2523, PA2641, and PA4650-FN outer filters for maximum flexibility across housings.
● Broad engine coverage — confirmed fit on Cummins, Detroit Diesel, Deutz, Fiat, and International engines across a wide range of construction and agricultural equipment.
● Gasket G103-N included — sealing hardware furnished in the box; ready to install immediately.
