Mirka, Hilti and Fein extractor hose sizes: Ø 27 / 32, 27 mm, 1-1/16 and 1-3/8 in — dimension sheet
Source: Xem Studio, https://xemstudio.com/objects/mirka-hilti-fein-hose-sizes/  (sheet CC BY 4.0)
Basis: Mirka and Hilti product pages; Fein hose listings from a retailer (secondary)
Catalog version: 2026-10-20

Sizes: see table below
- Mirka prints a pair, 'Hose Ø 27 mm / 32 mm', for its hose-and-connector and sleeve-set products and does not say which number belongs to which part. Hilti's page prints 27 mm without inner or outer. Fein's hose listings are from a retailer and say 'inside diameter' (1-3/8 in and 1-1/16 in).
- Fein's 1-1/16 in is 26.99 mm, the same 27 mm class Hilti and Mirka name. This is a computed unit conversion, not a stated equivalence.
- None of the three prints cuff lengths, steps or taper, so no file.
- Only the numbers each source prints are listed, in the source's own words for what they measure. 'Nominal family' is the maker's own size label; it is not a measurement. Hose 'ID / OD' is the hose body, 'cuff / connection' is the end fitting, 'tool or accessory port' is the other side of an adapter. Inch figures are as printed; the mm in brackets are 25.4 mm per inch. A taper is listed only where a source prints it, and none does. Xem does not make these parts; measure your own hose before you size an adapter.
