I'm looking at replacing the rubber gasket that goes around the outside edge of a lid, in a "floating lid" / variable volume stainless steel fermentation tank.
So, they are expensive as heck.
And they basically look like 10-speed bike tire inner tubes...
SO: Assuming proper fit, and cleaning, etc...
Would the material from which a common "rubber" (no longer actually rubber I'm sure) inner-tube leach bad stuff into wine must, given the PH, long-term contact, various additives, sugars, etc.... ?
