Gasket tankless hot water
I have a tankless hot water coil in a 1980s American Standard boiler.
The coil plate was leaking fairly steadily, so I took it off to find not much of a gasket left, one stripped bolt and one broken bolt (which I broke, of course).
I drilled and retapped and bought some nice new bolts, only to find that the gaskets are unattainable and no place offering gasket material sturdy enough to hold up.
I am on my third attempt: Number One, a modified gasket from a local heating supply company couldn't withstand my modifications and got chewed up when I bolted it down. Number Two, a better designed gasket taken from a pattern meticulously traced from the actual plate, performed even worse – possibly because it was only a 3/16 silicone affair.
So:
How thick should the new gasket be, what material should I use and where do I buy it?
I tried to search this on the Wall, but couldn't find any thing.
Thanks very much,
Al.
If that's an American-Standard boiler
it wasn't made in the 1980s. A-S sold their boiler line to Burnham in 1971 or so.
You might try an industrial supplier for some gasket material. They use some pretty heavy-duty stuff. Or, look at upgrading to a more-efficient boiler and indirect tank.

coil gasket
Everhot makes replacement coils for virtually every boiler out there and you should be able to get a gasket for it....just make sure of the boiler model
