FS111B3T125 filter element: specifications & equivalents

Q: What are the dimensions of the FS111B3T125 filter element?

The published envelope is 46 mm OD × 106 mm length (1.811 × 4.173 in). Confirm against the housing drawing before ordering.

Q: What micron rating does FS111B3T125 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 FS111B3T125 is a Filtrec inline-line hydraulic filter element, built with wire-mesh media, sized 46 × 106 mm OD × length, rated at 125 µm class. 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.

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 FS111B3T125 filter element?

The published envelope is 46 mm OD × 106 mm length (1.811 × 4.173 in). Confirm against the housing drawing before ordering.

What micron rating does FS111B3T125 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 FS111B3T125 filter element?

4 catalog-confirmed full match(es) (FA2512, FA25125, NA10M125…); 3 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.

These 11 catalog element(s) share the 46×106 mm envelope. Envelope match alone does not guarantee interchangeability — compare micron/Beta, seals and collapse rating.
