Hi all,
Have an interesting situation, I have a cool tube that is 4 1/2 in in diameter. I have some 5 to 4 reducers that I might use with thick weather stripping wraped around the tube but was wondering what other innovative solutions might be out there.

Thanks for your input :)
 
craft a 4 1/2 to 5 adapter, from thin sheet metal, and then use your reducer. weatherstripping may burn/melt and cause a fire or a mess. use caution, imo.

When using an ridged adapter I don't think that would work out too well and 4in ducting will not fit on the 4 1/2 couple. I thought about cutting the ducting and using tape to fill but that seems like a rather poor solution under use , I could be wrong and often am :)
 
Put a 4" round fish collar in the other pipe spread the metal tabs to center it and use spray foam to fill the gap, use window and door foam as it does not expand as much, ready to go in 3 minutes.

Cut a wood collar insert and screw, insert 4" pipe.

Any tin shop will make you one for 20$
 
I 5 inch and crimp it with ducting crimpers. Should bring it to 4 3/4. Tape it. Or get a 4 inch and place a rubber seal on the outside and force it inside the tube then tape. And where the he'll did you get a 4.5?

Yeah, I know :P It was very tempting. I just wanted something to that I could remove without hassle to change bulbs easily, ended up getting some high temp gasketing and sliding the adapters on.

Air-tight and works like a charm :)
 
Ok. I would be very careful of the glass. Might not be tempered. If you can keep your fan going at least 20 after lights go out. Also might seem airtight but I can tell you it isn't. You will put the smell out if you don't put HVAC tape (thick aluminum) around where the glass meets the metal. Go about 1/2 inch on to the glass. Setup looks clean.
