R310C05P filter element: specifications & equivalents
The R310C05P is a Filtrec inline-line hydraulic filter element, built with cellulose media, sized 154.5 × 457 mm OD × length (ID 54 mm), rated at 5 µm class (β5(c)≥2). Verify against the current manufacturer data sheet before ordering.
Dimensions and media grade are taken from Filtrec’s official Cross Navigator, which maps this element to specific competitor part numbers. Filtrec does not publish collapse pressure or seal compound in this API for every code — verify collapse rating, seal execution and bypass setting against the current Filtrec data sheet for the target housing before ordering.

How the R310C05P model number is decoded
- C05Filtrec internal media grade code (cellulose, 5 µm).
Typical equipment & applications
- Filtrec aftermarket replacement hydraulic/lube filter element (R family), form-fit-function cross-referenced in Filtrec's official Cross Navigator.
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.
- Fine 5 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.
