FS134B8T125B filter element: specifications & equivalents

Q: What are the dimensions of the FS134B8T125B filter element?

The published envelope is 86 mm OD × 260 mm length (3.386 × 10.236 in). Confirm against the housing drawing before ordering.

Q: What micron rating does FS134B8T125B use?

This element is rated 125 µm (nominal class). Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

The FS134B8T125B is a Filtrec inline-line hydraulic filter element, built with wire-mesh media, sized 86 × 260 mm OD × length, rated at 125 µm class. 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.

↔ SFE180G125A10BYP page in verification queue	Aftermarket	full	Filtrec's official Cross Navigator maps HYDAC SFE180G125A10BYP to FILTREC FS134B8T125B as a direct replacement, publishing the FILTREC element's OD/ID/height envelope and media grade.
↔ HF35171	Fleetguard	partial	Filtrec's official Cross Navigator maps FLEETGUARD HF35171 to FILTREC FS134B8T125B as a direct replacement, publishing the FILTREC element's OD/ID/height envelope and media grade. Rated micron differs (115 vs 125 µm) — verify efficiency class and collapse/seal for the housing before substituting.
↔ PT23179	Baldwin Filters	partial	Baldwin's Form 561 Number-Finder cross-reference lists FS134B8T125B (FILTREC) as replaced by Baldwin PT23179. Form/fit listing without published performance data — verify micron grade, collapse rating and seal configuration 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 FS134B8T125B filter element?

The published envelope is 86 mm OD × 260 mm length (3.386 × 10.236 in). Confirm against the housing drawing before ordering.

What micron rating does FS134B8T125B use?

This element is rated 125 µm (nominal class). Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

What replaces the FS134B8T125B filter element?

1 catalog-confirmed full match(es) (SFE180G125A10BYP); 2 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.
