Lube Filter P550078
The Lube Filter P550078 provides vital engine core security by isolating harmful combustion soot, fine metal shavings, and road grit before they can disrupt the protective oil film of precision internal components. Engineered as a direct technical match for the Donaldson P550078 element, this high-performance spin-on unit provides versatile cross-fleet flexibility. It is qualified to meet or exceed technical specifications across various major brands, including AC Delco PF1026A, Airman-Hokuetsu 9132400930, Alco SP842, and Allis-Chalmers 267272. It serves as a primary replacement for Toyota 1560133010 applications. Utilizing an optimized cellulose media structure tested under JIS D 1611 guidelines, this filter achieves a 50% efficiency rating at 20 microns. Equipped with a resilient built-in anti-drainback valve, it maintains oil retention within the filter assembly, successfully eliminating metal-on-metal dry-start wear and safeguarding heavy-duty drivetrains against costly premature breakdown.
