Part to stop leak coming from exhaust vents

[ArtWithin]

I'm attempting to stop a leak that seems to be coming in from the exhaust vent. There seems to be some boot or gasket that has deteriorated inside the vent. Does anyone know what this is called and where I can find it. I looked on Vintage Airstream Supply and could not find it.

That part is called a sewer vent pipe cover gasket.

They only last 2 to 3 years.

A screen is added over the pipe, then the gasket is slipped over the screen and pipe.

Then the gap between the gasket and pipe is filled with Vulkem sealer.

That gasket costs very little.

All of them should be replaced at the same time.
