RHK800M15B filter element: specifications & equivalents

Q: What are the dimensions of the RHK800M15B filter element?

The published envelope is 114 mm OD × 398 mm length with a 68.5 mm inside diameter (4.488 × 15.669 in × 2.697 in ID). Confirm against the housing drawing before ordering.

Q: What micron rating does RHK800M15B use?

This element is rated 20 µm absolute — β20(c)≥1000. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

The RHK800M15B is a Filtrec inline-line hydraulic filter element, built with synthetic media, sized 114 × 398 mm OD × length (ID 68.5 mm), rated at 20 µm absolute (β20(c)≥1000). Verify against the current manufacturer data sheet before ordering.

Catalog verified. Parameters extracted from the manufacturer’s electronic catalog / official interchange document and checked 2026-10-03. Confidence score 0.90.

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.

↔ 0800 RK 015 MM	HYDAC	partial	Filtrec's official Cross Navigator maps HYDAC 0800RK015MM to FILTREC RHK800M15B as a direct replacement, publishing the FILTREC element's OD/ID/height envelope and media grade. Rated micron differs (15 vs 20 µm) — verify efficiency class and collapse/seal for the housing before substituting.

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.

Frequently asked questions

What are the dimensions of the RHK800M15B filter element?

The published envelope is 114 mm OD × 398 mm length with a 68.5 mm inside diameter (4.488 × 15.669 in × 2.697 in ID). Confirm against the housing drawing before ordering.

What micron rating does RHK800M15B use?

This element is rated 20 µm absolute — β20(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 RHK800M15B filter element?

1 partial match(es) requiring parameter review

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.
