Series naming logic

The 51xxx part-number prefix identifies WIX heavy-duty hydraulic filters. Cartridge-style elements publish OD/ID/height (no mounting thread); spin-on executions publish a baseplate thread size. The WIX product catalog publishes Height, Outside/Inside Diameter, Thread Size, Media, Beta Ratio, Nominal Micron Rating, Burst Pressure and By-Pass Valve Setting for each part number.

Selecting within the 51xxx series

Pick the size code from the existing housing nameplate or from the old element’s overall OD and length.
Pick the grade to meet the target ISO 4406 cleanliness code — finer grades load faster and raise cold-start Δp.
Pick the collapse execution: low-collapse BN4HC for return housings, high-collapse BH4HC where pressure spikes demand it.
Confirm seals and bypass: NBR for mineral oils; check for an integral bypass valve before substituting executions.
