Universal Vacuum Hose Adapter Kit includes 5 pieces of converters, allowing for easy conversion from 3.81cm to 3.81cm and from 4.45cm to 3.25cm dust hose port adapters.

Adapters are very convenient for using certain accessories of a vacuum cleaner on the hose of another non-compatible vacuum cleaner.
I wanted to find this kind of adapter for my workshop so that I could connect the sawdust outlet of circular and radial saws as well as the sanders to a large hose mounted on a Nilfisk vacuum cleaner. It's impeccable and it works very well.

Really well made amd for the.price, great value.
Good delivery.
