Shop-vac hose sizes, 1-1/4, 1-7/8 and 2-1/2 in: RIDGID, Craftsman, Workshop, Milwaukee, Shop-Vac, Vacmaster, Stanley — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/shop-vac-inch-hose-sizes/ (sheet CC BY 4.0) Basis: RIDGID, Workshop (Emerson), Craftsman and Milwaukee product pages; retailer pages for the rest (secondary) Catalog version: 2026-10-20 Sizes: see table below - The inch family of shop-vac hoses is named by its size: 1-1/4 in, 1-1/2 in, 1-7/8 in and 2-1/2 in. The makers here print only that nominal size. None prints the hose's real ID or OD, the cuff OD or ID, or any taper. - A blog author measured a Shop Vac '2-1/2 in' hose at about 2.4 in without saying which diameter, so the nominal 2-1/2 in is not a verified OD or ID. DeWalt's DWV9190 page separately prints a 2 1/2 in (57.2 mm) hose OD; see the DeWalt page. - Makes and sizes that share a family connect through friction-fit or locking cuffs, but the cuff dimensions are not published. Armor All: no citable hose or accessory page was found, so it is not listed. - No file: no source prints a cuff, wand or lock-lug dimension for any of these, and a plain tube is not a valid 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. item nominal family hose ID hose OD cuff / connection tool or accessory port taper source RIDGID VT1720 hose, 7 ft, with 1-1/4 in adapter 1-7/8 in (adapts to 1-1/4 in) 1-7/8 in (hose diameter; ID/OD not stated) not published fits RIDGID inlets; adapts to 1-7/8 in and 1-1/4 in accessories 1-1/4 in adapter not published maker page RIDGID VT1721 expandable hose, 2 to 7 ft 1-7/8 in 1-7/8 in not published not published not published not published maker page RIDGID LA2520 hose, 7 ft 2-1/2 in 2-1/2 in not published fits RIDGID inlets; adapts to 2-1/2 in accessories 2 NXT locking adapters, drum locking adapter, friction-fit adapter (sizes not printed) not published maker page Workshop WS25020A hose, 7 ft 2-1/2 in 2-1/2 in not published not published not published not published maker page Craftsman CMXZVBE38763 hose, 7 ft 2-1/2 in 2-1/2 in not published 2 adapters, 2 friction-fit adapters, 1 hose-to-hose adapter (sizes not printed) not published not published maker page Craftsman CMXZVBE38758 POS-I-LOCK hose, 13 ft 2-1/2 in 2-1/2 in not published 3 adapters (sizes not printed) not published not published maker page Milwaukee 49-90-1984 hose, 16 ft 1-7/8 in 1-7/8 in not published not published not published not published secondary Milwaukee 49-90-1991 adapter kit (3 pieces) 2-1/2 in to 1-7/8 in not published not published 1-7/8 in to 1-7/8 in hose adapter; 2-1/2 in inlet 2-1/2 in to 1-7/8 in accessory adapter not published maker page Milwaukee 49-90-1980 dust extraction adaptor kit 1-7/8 in not published not published inlet diameter 1.875 in friction fit to power tool ports; 2-1/2 in table-saw ports not published secondary Shop-Vac hose 8 ft 1-1/4 in; also listed 1-1/2 in 1-1/4 in; 1-1/2 in not published not published not published not published secondary Vacmaster adapters 1-7/8 in to 1-1/4 in; 2-1/2 in to 1-1/4 in not published not published not published 1-1/4 in accessory side not published secondary Stanley 19-1400 crevice nozzle 1-7/8 in not published not published 1 7/8 in connection not published not published secondary Generic 1-1/4 in wand and 2-1/4 in dust port (Printables author) 1-1/4 in 1.25 in shop-vac hose not published not published 2.25 in output not published secondary, user model Shop Vac 2-1/2 in hose, blog measurement 2-1/2 in about 2.4 in; ID/OD not stated not published not published not published not published secondary, measured Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - RIDGID (US product page): 1-7/8 in. x 7 ft.
