Technical Details and Performance

The WL7503 oil filter features a cellulose media material that provides a 23 micron filtration rating, effectively capturing engine contaminants to protect critical components. Its beta ratio of 2=23 indicates the filter’s efficiency in removing particles of this size. The anti-drain back valve prevents oil from draining out of the filter when the engine is off, reducing wear during startup. The bypass relief valve is calibrated to open at 36 psi, ensuring oil flow continues even if the filter becomes clogged. With a burst pressure rating of 276 psi, the filter maintains structural integrity under high pressure conditions. The spin-on design with a 3/4-16 thread size allows for straightforward replacement in compatible vehicles.
