Ridgid makes some of the most popular shop vacs in North America. The WD and HD series are in millions of garages and job sites. If you have a Ridgid shop vac and power tools from Milwaukee, DeWalt, Makita, or Bosch, you need adapters to connect them cleanly.
Here is the complete guide to Ridgid shop vac hose sizes and how to match them to every major tool port.
Ridgid Shop Vac Hose Sizes
Ridgid uses three hose diameters across their product line:
| Model Series | Hose Size | Hose OD at Tool End |
|---|---|---|
| WD4050 (4 gal), WD0671 (6 gal) | 1-7/8 inch | 48mm |
| HD0900 (9 gal), WD1450 (14 gal) | 1-7/8 inch | 48mm |
| WD16 (16 gal) and larger | 2-1/2 inch | 63mm |
| Ridgid OCTANE (portable) | 1-1/4 inch | 32mm |
The 1-7/8 inch hose is the standard on most mid-size Ridgid models. The tool end of that hose is about 48mm OD. Every common power tool port is smaller, which is why an adapter is needed. The port size hubs show which size your tool lands on.
Connecting Ridgid to Milwaukee M18 Tools
Milwaukee M18 FUEL tools sit on the 1-1/4 in. port hub. Your Ridgid 1-7/8 inch hose end is 48mm OD. The hose end is far too big to go into the Milwaukee port.
What you need: a 32mm-to-48mm step-up adapter. This fits in the Milwaukee port and accepts the Ridgid hose end (48mm OD). Both ends fit snug, which keeps air leaks to a minimum.
Connecting Ridgid to DeWalt 20V MAX Tools
DeWalt 20V MAX hand tools sit on the same hub as Milwaukee. Same situation. One adapter carries your Ridgid 1-7/8 inch hose to any DeWalt 20V MAX circular saw, sander, jigsaw or router.
Connecting Ridgid to Makita LXT Tools
Makita LXT tools sit on the 36mm port hub. Your Ridgid 1-7/8 inch hose is 48mm OD. The Makita port is a little bigger than the Milwaukee and DeWalt ports and still much smaller than the Ridgid hose end.
What you need: a 36mm-to-48mm adapter. This seats in the Makita port and receives the Ridgid hose (48mm OD).
Connecting Ridgid to Bosch and Metabo HPT Tools
Bosch and Metabo HPT share the 35mm port hub. Same solution: one adapter carries your Ridgid hose to any Bosch or Metabo HPT tool.
Connecting Ridgid to Festool Tools
Festool tools sit on the 27mm port hub, the smallest common tool port. Your Ridgid 1-7/8 inch hose end (48mm OD) dwarfs it. The adapter has a narrow end for the Festool port and a wide end that takes the Ridgid hose.
Note: connecting a non-HEPA Ridgid shop vac to Festool tools means fine dust can pass through the Ridgid filter. Festool recommends using their own extractors for Class M or H work. If you use a Ridgid vac for regular sanding, add a HEPA filter bag to the Ridgid unit.
Ridgid Shop Vac Filters
Ridgid shop vacs come with two filter types: the cartridge filter (round, dry use) and the foam filter (wet/dry use). For dust collection from power tools:
- Remove the foam sleeve when doing dry dust work. The foam restricts airflow and is not needed for sawdust.
- Use the cartridge filter only for dry work. Water destroys the paper cartridge.
- Add a HEPA filter bag for fine dust from sanders and routers.
Ridgid model VF5000 is a HEPA fine dust filter replacement that fits several Ridgid shop vac models. It is a direct upgrade over the standard cartridge for shops where sanding is common.
Some Ridgid models have a shake-to-clean feature built into the filter collar. Press the button to tap the filter and knock loose dust after each session. This cuts down on how often you need to pull the filter for a full cleaning.
