Title: Exhaust gaskets: Copper or alu/fibre?
Post by: AndyH on May 24, 2020, 08:43:35 AM: Refurbing my exhaust system and need to purchase new exhaust gaskets.
I can obtain both copper, or aluminium/fibre items at the same price.
Which is considered to be the best?
TIA!

Purely a preference.
No real reason

That reminds me of an audit I was involved in on one of the ships I was on. The auditor was going through the stores list and came accross an entry for “CAF” jointing. CAF stood for compressed asbestos fibre. He asked, “Why did we have asbestos on board?” It wasn’t asbestos, the old terminology had been wrongly used. Thinking on my feet I said, “ CAF, completely asbestos free”. Thankfully he saw the funny side.
