Does anyone know what I should use to connect my bath fans to PVC pipe. Someone suggested a Fernco coupling but a 3″ fernco fits perfect on the PVC but it’s too big for the fan’s exhaust outlet.

glue on a piece of 3" to the fan housing...

The 3" pvc is about an 1/8" bigger than the fan housing. So I don't think I'd get a good seal gluing it.I would just rather use PVC instead of metal ducts. It seems like PVC is easier to work with (cut/glue), would seal better and I have a bunch left over from doing my sewer lines.
take Mr Doud's recomendation...

"Seems like it would be easier to work with"...well evidently not :)
I used the black rubber hose with the hose clamps for ductile pipe.two ways to screw up concrete 1) concrete driver 2) concrete finisher
Yeah, it sounds like I've made this more difficult than I intended. I'll try and explain this a little better. I've read on the forums a couple of times where someone recommended using pvc instead of metal ducts for the fan vents. My only problem is that the fan housing is made for a 3" metal duct. 3" schedule 40 pvc has an inside diameter of a little over 3" so I can't exactly glue the two together. Then I read somewhere to use a fernco coupling... but they're sized to go on the outside of pipe (3" pvc = 3.5" outside diameter") So the fernco would fit great on the pvc but not on the 3" fan housing. I thought using pvc was a fairly common practice but I guess at this point I may just try and increase the diameter of the fan housing or just use metal duct.thanks!
I used sch 40 PVC for my bath fans. IIRC, I used a PVC coupling which fit over the fan outlet loosely. Close enough fit that a bead of caulk sealed it. http://grantlogan.net/

Only reason I used PVC was that I had all the parts on hand. So, I was done before you got back from the supply house with change in my pocket..http://grantlogan.net/

I've been trying to convince our electrician that the exhaust vents are his responsibility.............. but no luck.
I'll tell you what many people mean when they say not to use metal duct, especially for dryer vents and that is the corrigated flexible type. Small sections of it however can be used to isolate vibrations better.
why not rigid vent pipe/snap loc???...

this is a place to use your duct tape - wrap it around the fan exhaust outlet till the Fernco fits -
Why not just use insulated duct?
The instructions on my new Panasonic bath fan recommend using a short piece of flexible duct to connect the fan outlet to the rigid exhaust pipe, possible noise transmitted and amplified by the rigid connection.
Heat the end of the pipe and stretch it.
Burner on the stove works, keep rotating it till it's soft.
