How the 57231 model number is decoded

  • 57231WIX hydraulic cartridge element part number.
  • 105.9 mm OD / 10.4 mm IDCartridge envelope (outside/inside diameter); no mounting thread.
  • Wire/GlassFilter media: Wire/Glass.

Typical equipment & applications

  • Mobile and industrial hydraulic return circuits
  • Construction and agricultural equipment
  • Heavy-duty transmission and torque-converter circuits

Selection pitfalls — read before you substitute

  • A return-line element is not a pressure-line element: return cartridges (low-collapse) tolerate roughly 20 bar differential, while BH4HC pressure executions are rated to 210 bar. Installing a low-collapse element in a pressure housing can rupture the media on cold-start spikes.
  • This element has no integral bypass — opening pressure is set by the housing’s reusable bypass valve. Confirm the valve setting (commonly 3.4 bar) is present before fitting.
  • “10 µm nominal” and “12 µm at β1000” can describe the very same media — one is reported at β≥200, the other at β≥1000 per ISO 16889. Compare ratings at the same Beta test point, not just the printed micron number.
  • Nitrile (NBR) seals are standard for mineral hydraulic oil but fail early in some phosphate-ester fluids and at sustained high temperature; verify seal compound against the fluid data sheet (fluorocarbon/Viton executions may be required).
  • End-cap geometry and the number/position of O-rings block interchange even when OD and length match — visually compare end caps before fitting, especially with aftermarket cartridges.

Frequently asked questions

What are the dimensions of the 57231 filter element?
The published envelope is 105.9 mm OD × 464.8 mm length with a 10.4 mm inside diameter (4.169 × 18.299 in × 0.409 in ID). Confirm against the housing drawing before ordering.
What replaces the 57231 filter element?
Cross references are being verified for this model — use the inquiry form and the engineering desk will confirm equivalents.
How do I read the 57231 part number?
See the designation decoder above: each segment of 57231 encodes size, line type, filtration grade and media/collapse execution.
Is a same-envelope aftermarket element always a drop-in replacement?
No. Matching OD and length only proves the cartridge fits the bowl. End-cap style, seal compound, micron/Beta rating, collapse pressure and bypass configuration must also match; the table above tags every equivalent as full, partial or verify for exactly this reason.
How often should a hydraulic return-line element be replaced?
Replace at the housing manufacturer’s recommended differential-pressure setting (commonly signalled by a clogging indicator), or on a time-based service interval when no indicator is fitted — never wait for bypass to open continuously, because unfiltered oil then reaches the valves.
