About This Part

A stepped adapter that fits the three hose sizes most shops use: 2-1/2, 1-7/8, and 1-1/4 inch. The steps get smaller going up. Push your hose onto the step that matches it and it seats snug.

Use it to step your shop-vac hose down to a smaller tool port, or the other way around. The bore steps down inside too, so the air path stays open.

It prints upright with no supports, wide end on the bed.

Who it is for: Anyone juggling more than one hose size on a shop vac or dust collector.

Universal Step Adapter FAQ

How does the step adapter work?+

It has three steps, each a different size. Push your hose down onto the step that matches its size and it grips there. A big hose slides down to the wide step, a small hose stops on the narrow one.

Can it connect two different sizes?+

Yes, that is the point. Put your hose on the step that fits it, then connect the other end to your smaller tool port or fitting. The air steps down through the middle.

Which sizes does it fit?+

The three most common shop sizes: 2-1/2 inch, 1-7/8 inch, and 1-1/4 inch. If your hose measures a little different, tell us and we tune the fit.
