Five Adapter attachments included. We had these designed to fit most standard vacuum hoses up to 1 3/4 inches and then we added a Generic Shop Vac Attachment and another common size adapter. We designed these to fit most vacuum hoses.
The 4 adapters will fit into each other to make a variety of connectors. Just try one till it fits. The smallest size they will fit is 1 1/16 inches up to 1 3/4 inches. Generic Shop Vac adapter is 1 1/4 to 2 1/2 inches. Small adapter is 35mm to 32mm.
Connect two together to make one adapter or connect all three together to make one adapter. One by itself might be all you need. Use these as a converter for your attachments to connect to your vacuum hose.
These vacuum connectors are made out of flexible plastic and have either a tapered fit or a step fit. The generic shop vac and small adapter is hard plastic. The 3 larger ones have some give in the plastic.
Use these to connect your power tools vacuum port to your hose in your work shop or with your shop vacuums. A common use for these adapters is connecting your vacuum hose to fit cleaning accessories and attachments.
