Oil Filters

The SO434 is a standard spin-on oil filter, applied to automotive engines, light commercial vehicles, agricultural machinery and small industrial diesel engine lubrication systems. It can effectively intercept metal debris, carbon deposits, sludge and tiny impurities in engine oil, keep the lubrication system clean, reduce wear of engine components, and maintain stable long-term operation of equipment.

Key Features

Adopts high-performance cellulose composite filter media, with stable filtration precision and large dirt holding capacity to extend replacement cycle.

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

Equipped with internal bypass valve to ensure normal oil supply during cold start or filter blockage.

High-strength stamped steel shell, pressure-resistant and deformation-resistant, adaptable to various conventional working conditions.

Premium nitrile rubber sealing ring, good aging resistance, tight fitting and excellent oil leakage prevention.

Standard overall size and thread specification, easy to install and replace, no modification required.
