Adaptor: garden hose (GHT/NHT 3/4-11.5) male to small shop vac female.
You could use this to connect a wet vac to a garden hose. I use it with a cast-off water balloon filler as a vac attachment for small parts drawers. The kids sometime get these automatic water balloon fillers (second photo) that generate so much plastic waste. I thought of a way to reuse the nozzle as a vacuum attachment that won't suck up screws and items from a small parts drawer or tray.
The pink part is the water balloon filler waste that connects to a garden hose (GHT/NHT 3/4-11.5). My adaptor threads into it and connects to any small shop vac or dust extractor hose.
