I just bought a Super Dust Deputy. Its 5" inlet and 6" outlet are causing me big probs.

I have 6" hoses off my machines so I bought an HVAC 6" to 5" reducer (uncrimped at both ends).

The SDD's inlet is 5" (actually it's 5 1/8). And the SDD's outlet is 6" (really it's 6 1/8"). My hose won't fit over it either.

What is your advice to modify SOMETHING/ANYTHING to get these things to fit efficiently.

And - what are your thoughts re any advice so I can get this going fast -
- how much extra room do I acquire if I buy crimped reducers and "un-crimp" some of the crimps
- does it make sense to drill out the reducer's rivets, move the collar a little and use a #4 screw to hold it in the new position
- where to buy rubber-type plumbing 6" to 5" reducer fitting

Thanks

I have the same sort of set up and here's a couple of options:

1. PowerTec coupler: Powertec coupler on Amazon
Listing shows the OD of the coupler at the 5" end to by 4 7/8" which I think should slip inside the SDD inlet.

2. Fernco style coupler: Rubber coupler on Home Depot%
Specs say the IDs are 5.5" and 4.25" but you should be able to crank them down. But you'll need a piece of 4" hose coupler to attach the hose.

3. Duct Reducer: Reducer at HD
This is what I'm using and was able to open up the 5" end slightly by rotating it over a piece of steel pipe to flare the 5" end slightly. It fits very very tightly over the SDD inlet after flaring it a little. I chose this as it was immediately available at the HD, but it also has the advantage of a smoother transition.

I'm sure there are some higher $ options like a nordfab reducer that would work as well, but the metal reducer above works fine and you could always cut a few slots in the 5" coupler section to give it a better fit and then seal it with tape. I'm using tape in any case to make sure I have a good seal.

sorry, just realized you wanted 6" down to 5" so my post may not be all that helpful. I'll leave it up anyway as it may be useful to someone, but I think the same logic applies using a 6" to 5" reducer and short piece of 6" duct for the hose attachment. The 5" end could be crimped down just a bit to go in the SDD inlet I think.

5" sized ports/fittings are hard to find.
I started a thread attempting to document what I could I find.

If you want rubber couplings; the Fernco Master catalog of standard parts is easy to use. I think there is a better option, but you can make a 1056-65 convert from 6" to 5". Need big squeeze on band clamps to close down OD on each end, but it will work.

BTW - not sure you will like the impact your SDD creates? If all machine connections are 6", and SDD inlet is 5"; you will slow down airflow increasing the size from 5" port to 6" hose to machine. This is not recommended practice in dust collection plumbing? Why not use the Dust Deputy XL that offers 6" inlet and outlet ports?

Best Luck.

If I recall correctly, Oneida just happens to have a pretty decent selection of adapters. They aren't cheap though.

My solution was to take the SDD to the local big box store or some place that sells Fernco rubber adapters and wander the aisles trying out the fittings until you find something that works. I've also had luck with the thin wall rigid drain pipe and fittings that can be found in the garden centers of the big box stores.

You might also consider getting some hose from Oneida.

Hi all,

I think I solved my Super Dust Deputy problem

- 6" hose will fit perfectly directly on the SDD's outlet
this requires close to nil in the way of wrestling the hose onto the inlet
you just have to reeeeeally open up the clamp

- Oneida supplies a 5" collar to use for installing duct rather than hose onto the inlet
- it fits perfectly onto the uncrimped 5" side of the 6" to 5" reducer
it seems you still need to tape it up to close things off leaks etc

- this now poses 2 questions/opportunities/problems
I'll need to break down and just buy 5" hose and fittings to replace the 6" hose and use it the way it's designed
(admittedly, rather unusual in the typical Rosenberg Brain Process way of doing things)
and just say goodbye to my 6" hose and fittings

As I continue to get myself organized, I'll keep you posted.
