My foreman told me to always use a 3/8-inch gap on the gasket for that old Babcock & Wilcox boiler in Toledo, and I should have listened.
He said it was a quirk of that specific model from the 60s, but I thought my usual 1/4-inch seal would hold just fine. The pressure test blew the gasket right out after about 20 minutes, and we lost half a day redoing the whole flange. What's the weirdest model-specific trick you've been told that actually worked?

That "quirk of that specific model" thing is so real.

Man, that's a rough way to learn a lesson. Did your foreman ever explain why that particular boiler needed the bigger gap? Was it about how the old metal expanded differently under heat, or something else entirely?
