Need 30" bellows

[Plasmech]

I'm in need of a 30" inside diameter x 20" long bellows to be used for sealing (not a perfect seal). Temp rating must be 250F. Anybody have any ideas? Thanks.

You need a flue duct expansion joint. Here is just one of many manufacturers of these items.

AFJ in Australia have supplied joints like this in the past.

Made a trip to the plant today while there checked on some non-metallic expansion joints in use.
The ones that were in use were the Teflon lined type but was told that they make an unlined one tha will take your temperature.
