4"x4" Duct Pipe

[Amber Gold]

Where can I find 4"x4" duct pipe? I need it to plumb from the high pressure blower to the evaporator. Need <24" of it.

Thanks

You can use corrugated aluminum duct, like for dryer vent. Easy to bend into position,a nd can be formed to square and clamped to square tube if needed.

I would get in contact with anyone who installs furnaces they could probably make what ever you need

Check Home depot in the drier duct area. I saw some that was square on ends and round between. Otherwise in the same area there is ducting and all kinds of transitions for floor registers.
