**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- Bosch Professional's pages print a single 'Diameter' for each sleeve and say neither inner nor outer. The connector 1 600 499 005 is a 35 mm to 25 mm reduction adapter; the page prints 25 mm minimum and 35 mm maximum.
- The machine adapter for the GAS 35/55 is described as joining 22 mm and 35 mm; the retailer's text also says 19 mm tubes once, so it is shown as conflicted.
- Bosch does not publish wall thickness, length or bayonet lug sizes on these pages, 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.
