Wondered if anyone could help with muffler

[johnnycosmos]

Hi,

Prafa nitro. Works well but exhaust shook loose while tuning.
Parts almost impossible to find.

The two bits pictured had a ‘o’ ring between them which has degraded.

Any ideas? Is there a standard seal? Do the new ish liquid gasket things work?

Forgive dirty fingernails!
Many thanks

John

You can probably get away with some high temp RTV after cleaning the mating surfaces up. Put it on, assemble the pipe and let it cure overnight. It's what's typically used to to help seal backplates and carb necks.

Sensor safe doesn't emit an acidic vapor as it cures which is what I linked.

I was thinking High Temp JB Weld also.

The long cure jbweld works for that kind of stuff as well, but it's a more permanent bond.
