Shoutout to the old-timer who insisted on using a copper gasket on a high-pressure steam line
I thought it was overkill compared to graphite, but after it held through a 3-day pressure test at the plant, I'm convinced. What's a piece of old-school advice that's actually held up for you?

Overkill compared to graphite" is exactly what they'd say before the graphite fails. Old guys with their copper gaskets are just built different, they've seen what happens when the new stuff doesn't work. Sometimes the old way is just the right way because it's boring and reliable. I'll take a boring win over a cool failure any day.

Old guys with their copper gaskets" is a bit of a myth, they fail too if the flange face isn't perfect. Graphite works great in a lot of modern applications where things are actually flat.

That line about boring and reliable being better than a cool failure hits hard. See it everywhere now, not just gaskets. People chase the shiny new fix for everything. @lily_cooper is right that the surface matters more than the material half the time. But we keep buying the complex solution because it's marketed as better. Sometimes the simple, tested way just works because it has fewer parts to go wrong. It's not about old vs new, it's about proven vs promised.

Exactly. Had a coolant line on an old press that kept weeping with the fancy seals. Swapped in a simple copper crush gasket and torqued it to the old manual spec. That was five years ago. Not a single drop since. Sometimes the new thing just adds points of failure.
