Oil Filters

The SO115 is a standard spin-on oil filter, suitable for automotive engines, light commercial vehicles, agricultural machinery and small industrial diesel engine lubrication systems. It effectively filters metal particles, carbon deposits, sludge and fine impurities in engine oil, keeps the lubrication system clean, reduces internal parts wear, and maintains stable engine operation.

Key Features

Adopts high-quality cellulose composite filter media, with stable filtration accuracy and large dirt holding capacity to extend service life.

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

Internal bypass valve ensures smooth oil supply under cold start or filter clogging conditions.

Integral steel shell structure, pressure-resistant and not easy to deform, adapting to daily and light working environments.

Premium nitrile rubber sealing ring features good aging resistance and tight fitting, effectively preventing oil leakage.

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