Shop Vac Hose Adapter for 32mm Hose

These are custom adapters to fit the 32mm corrugated vacuum hose with a left hand thread to the corrugation. The adapters are in 30, 40 and 50mm versions and have a very slight taper to the inside edge to ensure a tight fit.

The hose I have is from here but I'm sure the same is available from other places.
