Title: discussion on copper gaskets
Post by: daveismissing on May 25 2018, 09:37:18 PM: I see people claiming to make various gaskets from copper stock. I can't think of any flange on a car that supports a large enough bolt to exert forces that crush a piece of copper. If a very soft copper "gasket" has an embossed/debossed area I could see that flattening to create a seal but otherwise....

Comments?

This is why I have moved to v-bands. I just put the whole exhaust back on the wagon in under an hour yesterday - leak free.
