How the 4.06.05 D 10 BH4 /-V model number is decoded

  • 4.06.05 D 10 BH4 /-VHYDAC Betterfit filter element ordering code per catalog.hydac.com. Replaces Parker elements.
  • BH/HC=Betamicron® High CollapseFilter media and collapse family as printed in the catalog.
  • 10 µmAbsolute filter rating per the HYDAC catalog.
  • 55.9 mmOutside diameter.
  • 134.6 mmElement length.
  • 210 barElement collapse (differential pressure) rating.
  • Fluorocarbon (Viton)Seal compound.

Typical equipment & applications

  • HYDAC Betterfit drop-in replacement for Parker hydraulic filter elements
  • Pressure-line filtration for equivalent housings

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 4.06.05 D 10 BH4 /-V filter element?
The published envelope is 55.9 mm OD × 134.6 mm length with a 36.3 mm inside diameter (2.201 × 5.299 in × 1.429 in ID). Confirm against the housing drawing before ordering.
What micron rating does 4.06.05 D 10 BH4 /-V use?
This element is rated 10 µm absolute — β10 > 1000 (HYDAC grade convention: β12(c) ≥ 1000). Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.
What replaces the 4.06.05 D 10 BH4 /-V 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 4.06.05 D 10 BH4 /-V part number?
See the designation decoder above: each segment of 40605D10BH4V 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.
