Excellent fitting upgrade for my Super Dust Deputy
I installed a Super Dust Deputy Deluxe a couple months ago (4” inlet, 5” outlet, model just before Oneida’s recent design change) and used this to replace the 5-to-4 reducer it came with. The Powertec reducer is stronger, stiffer, and has longer flanges. It fit maybe just a tad looser in the outlet opening than the cheap one supplied with the Dust Deputy, but since it was going to be caulked in anyway, it didn’t matter. A bead of silicone caulk around the 5” opening end and another just below the midpoint lip in the fitting and it’s solid as a rock in the Dust Deputy outlet opening. No issues getting my 4” hose to the fan inlet onto the fitting. Really satisfied and glad I upgraded the original reducer.

Works perfect for reducing 5” flex hose to 4” DWV PVC
Worked perfect for reducing the 5” flex hose running from the intake on my dust collector to the 4” DWV PVC I have run throughout my wood shop. Noticed a major improvement in suction throughout the shop as compared to using the 5” to 4” Y adapter that came with the dust collector that went on the intake.

Good Build Quality
Great construction and build quality. It does not fit directly in a Powermatic 209 planer without a piece of hose to connect the two. This is my fault because I did nt bother to measure the opening to the 64th of an inch. Overall happy with the product.

Fit was exactly what I was looking for
Used this adapter to adapt a 5" filter opening to my 4" dust collector hose. The fit was very good and the materials used seem nicely robust.

Inside diameter
Product diameter inside was not large enough needed to have an inside diameter of 5 in

Works as advertised
I needed a reducer for a European wood working machine and this works OK with a small adjustment to make it fit.
