Protect compatible Onan engines and generators with the WIX 57398 full-flow spin-on lube filter. Its cellulose media, anti-drainback valve, and 8 PSI bypass valve provide dependable oil filtration and lubrication-system protection.
The WIX 57398 is a full-flow spin-on lube filter designed for select Onan applications. Its cellulose filter media captures contaminants circulating through the engine oil while maintaining the flow required for proper lubrication during operation.
An integrated anti-drainback valve helps retain oil in the filter when the engine is shut down, while the built-in 8 PSI bypass valve maintains oil flow if restriction becomes excessive. A durable spin-on design and attached sealing gasket make routine filter replacement straightforward.
