WG604 filter element: specifications & equivalents
The WG604 is a Filtrec inline-line hydraulic filter element, built with glassfiber media, sized 189 × 561.5 mm OD × length (ID 123 mm), rated at 22 µm absolute (β22(c)≥1000). 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 WG604 model number is decoded
- G25Filtrec internal media grade code (glassfiber, 22 µm).
Typical equipment & applications
- Filtrec aftermarket replacement hydraulic/lube filter element (WG 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.
