Oil Filters

The W950/1 is a heavy-duty spin-on oil filter, suitable for industrial diesel engines, construction machinery, commercial vehicles and lubrication systems. It effectively removes metal debris, carbon deposits, sludge and fine impurities from engine oil, keeps the lubrication system clean, reduces parts wear, avoids pipeline blockage, and maintains stable engine operation.

Key Features

Adopts high-performance composite filter media, with accurate filtration precision and large dirt holding capacity to extend service life.

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

Internal bypass valve ensures continuous oil supply during cold start or filter clogging.

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

High-quality nitrile rubber seal ring provides tight fitting, aging resistance and excellent oil leakage prevention.

Standard overall size and thread specification, easy installation, direct replacement without any modification.
