Hi, I built a mashtun more or less the same as the one featured in FlyGuy's guide. I wasn't able to get it watertight until I used a rubber fender washer behind a metal one. Will that be okay, in terms of both flavor and chemical leaching, for the beer? I haven't tested it with hot water yet, but I plan to try that tomorrow morning.
I did see a neoprene washer, but I've heard those can contain a large amount of lead. I'm using brass fittings, though, so I guess I'm already at risk for neurological dammage.
