How the HPX0505A06ANP01 model number is decoded

  • HPX050MP Filtri element series and size code for the matched high/medium-pressure housing family.
  • 5Element length code within the series.
  • A06Filter media: Inorganic microfiber, 6 µm (absolute rating per ISO 16889).
  • ASeals: NBR (nitrile).
  • NElement differential-pressure (collapse) rating: 20 bar standard execution.
  • P01MP Filtri standard catalogue item execution.

Typical equipment & applications

  • Pressure-line hydraulic filters upstream of control valves
  • High-differential-pressure industrial hydraulic circuits
  • Hydraulic power units for steel, paper and power generation

Selection pitfalls — read before you substitute

  • “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 HPX0505A06ANP01 filter element?
The published envelope is 50 mm OD × 329 mm length with a 24 mm inside diameter (1.969 × 12.953 in × 0.945 in ID). Confirm against the housing drawing before ordering.
What micron rating does HPX0505A06ANP01 use?
This element is rated 6 µm absolute. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.
What replaces the HPX0505A06ANP01 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 HPX0505A06ANP01 part number?
See the designation decoder above: each segment of HPX0505A06ANP01 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.
