generator flexible bellows exhaust assembly
Hello, I searched through the older posts and I was not able to find the supplier for the welded bellows exhaust pipe used on the generator. I remember reading the name and contact information someone posted a couple of years ago.
Does anyone have a reccomendation?
I have seen what I am looking for on generators in Marathon coaches.
Thanks, Bandsaw.

Do a search under flexible exhaust tubing.

Jon, thanks for your reply. I have done several net searches. I will go back through all of the old posts and find the company name. I want the high quality assembly that is proven. I was hoping the person who gave the supplier name would read my message and save me the effort of digging in old posts.

I know of two types. One is a stainless steel tube with a flexible formation that allows it to flex around the formation. The other more commonly used type is a tube made of a strip of material (steel, stainless, etc) wound to form a flexible tube.
The first configuration is claimed to be leak free and I suppose it is but I am not sure if its original intent was to be constantly flexed and straightened as it is in a generator application. The second configuration obviously will not hold air pressure because it is a spiral wrapped construction but it flexes readily and can be used with constant bending and straightening.
I have had the second configuration on all my coaches and so far so good, I have never had a need to replace any. In fact I cannot recall any problems with the spiral wrapped flex tubes ever, but the solid tube with a flexible formation is used on the turbo inlet tube on 8V92 engines and speaking from experience that part is a routine replacement and the price is breathtaking.
