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.
