Oil Filters

The 71112111-48100 is a high-performance spin-on oil filter, specially developed for industrial diesel engines, construction machinery and agricultural equipment lubrication systems. It effectively removes metal debris, carbon deposits, sludge and tiny impurities from engine oil, keeps the lubrication system clean, reduces component abrasion, avoids pipeline blockage, and maintains stable long-term operation of the engine.

Key Features

Adopts high-density composite filter media, featuring high filtration accuracy and large dirt holding capacity to extend service cycle.

Built-in anti-drain back valve prevents oil backflow after engine shutdown and avoids dry start damage.

Internal bypass valve ensures continuous oil supply during cold start or when the filter is clogged.

Reinforced thick steel shell is pressure-resistant and deformation-resistant, adapting to harsh working conditions.

Premium nitrile rubber sealing ring provides tight fitting, aging resistance and excellent leak-proof performance.

Standard dimension and thread design enable quick installation, perfect direct replacement without modification.
