0250 DN 003 BH4HC filter element: specifications & equivalents
The 0250 DN 003 BH4HC is a HYDAC pressure-line hydraulic filter element, built with bh/hc=betamicron® high collapse media, sized 78.7 × 248.9 mm OD × length (ID 40.1 mm), rated at 3 µm absolute (ßx(c) ≥ 1000 (HYDAC grade convention: β5(c) ≥ 1000)). Verify against the current manufacturer data sheet before ordering.
Dimensions, ratings and seal compound are taken directly from the HYDAC electronic catalog (catalog.hydac.com). Outside diameter and length are converted from the inch values printed on the catalog page; verify against the current HYDAC data sheet before ordering.

Selection pitfalls — read before you substitute
- Line type is not interchangeable: return-line cartridges are low-collapse executions that typically tolerate roughly 10–20 bar differential, while pressure-line elements are commonly rated 100–210 bar. Installing a low-collapse element in a pressure housing can rupture the media on cold-start spikes.
- “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.
- This execution uses nitrile (buna-n) seals — verify the compound against the fluid data sheet: standard nitrile (NBR) can fail early in phosphate-ester fluids and at sustained high temperature, where fluorocarbon/Viton executions may be required.
- Fine 3 µm media loads faster and runs at a higher cold Δp than coarser grades — only downgrade cleanliness targets if the system ISO 4406 code allows it.
- 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.
