nirtic acid proof stopper

[etack]

I recently got a keg of acid and transferred it into glass 5 gallon carboys but it is eating though the stoppers that I have in them. What chemical resistant stoppers are there to buy and will silicone work as a stopper.

For now just to stop the bleeding you could wrap those stoppers with aluminum foil. Make sure the stopper is still air tight though.

yeah I have thought of that but the bottom part is all bubbly and sticky. I will get new white rubber ones and do that till I can get a more permanent solution. I was thinking of putting it in soda kegs if need be. the silicone bungs that I have found that say they are nitric resistant all have a though hole or are 35-40 dollars apiece.

I like teflon tape.
