I was in an appliance parts store and they had several pieces of
heating duct in the corner, including a piece that I will need two of.
This place doesn't sell the stuff. It was just stored there.
It is like a very short rectangular HVAC interior duct, that clamps to
metal ducts at each end, and has 4 inches of heavy vinyl in between.
Like 15x20x4 inches.
Is there a name for what I saw?
It's meant to go between the furnace/AC and the rest of the house
metals ducts, partly so furnace vibration won't get transmitted to the
house. Although it seems not every installer uses them.
The label on it said flex duct but when I looked that up on the
web all I found were long truly flexible ducts with built-in
insulation that contractors now use sometimes to go from the main duct
to individual rooms.

"I don't know. They're not mine."
Find a distributor that carries Standex duct fittings. The "Snappy"
(trade name), catalog is pretty much the standard around here. Here is
the catalog page with the duct connectors. Any good heating/plumbing
house should have them, or can order the size you need.
Oh, wow, yes. That's the picture and I'm pretty sure the dimensions
are in that list. Thanks a lot.
For the record, the dimensions are that of the duct it is mating with,
measured NOT at the very end, right? That is, without any cleats on
there now or anything else that might make the end bigger than the
Hey, they even have an "Upcoming event" in Baltimore, although it was
last September! ;)
It is used to isolate noise from one part of the system into another
part of the system. It is frequently found on the input and output
sides of the main duct fairly close to the furnace/air conditioning
unit to isolate motor/fan noise.
