I bought this guy and I would like to have the option to vent outside so I need to run a hose or some pipe to outside.
Any idea if there is such a thing like 3.5” hose?

Get the 4” hose and use duct tape to make it fit.

Can I use a hose clamp when the hose is larger?

You can if you’ve put the duct tape on the DC outlet, it will squeeze the hose into the tape. I recommend the wire type clamps, they’ve always worked better for me than the band type.

Oh that is what you meant by use tape :-) so I need to add 0.25” of tape all around …that could be a lot of tape but yes that could be a solution. The other would be to try to mold a 4” but I doubt it would work. I still have to go to Home Depot to look at he fittings for gas and water I thin they measure the Internal Diameter ..maybe I can find something close

I could try to mold a cut open pipe section like this
I might need to add two layers there which is not a fantastic solution

Look at fernco or other brands of rubber plumbing couplings. Many odd sizes available, even some to for old clay sewer pipe. You may need a short piece of hard pipe between the rubber coupling and 4” hose.

the 3”to3” rubber coupling works just fine. The an 3×3 elbow gas pvc fitting (male toward the DC and female to outside) and then a 3”to4” adapter did the job. I now have the option to run the exhaust straight out using a 4” pvc gas pipe, no molding no gluing
