FAQ
How can I ensure this valve plate fits my vehicle?
Vehicle model alone may not be sufficient. You should check the OE number on the compressor housing and compare the port count, layout, and thickness with your removed part.
What systems is this component compatible with?
This valve plate is designed for use in Mercedes-Benz CITO (O 520) vehicles with OM 904 LA engines and is compatible with WABCO systems.
What are the symptoms of a faulty compressor valve plate?
A worn or damaged valve plate can lead to slow air pressure build-up, inconsistent air delivery, or audible air leaks from the compressor housing.
Can I use any valve plate for this compressor?
No, it is critical to match the port configuration and thickness. Always rely on the OE number from the compressor rather than just the vehicle model to ensure a correct fit.
