Hey, Haven't been here for a while. Got a swing top ??? Got some swing tops and they worked fine, the first time. I didn't change the gaskets for the second use and about 1/2 didn't seal well- flat beer! yuk! Just added a couple of Cooper tabs, changed the gaskets and the beer was fine after re-conditioning. Later I read somewhere that the problem was the orginal gaskets. They are a different material than the replacement gaskets I purchased. Question is- how many times can one re-use the rubber gaskets? I hate changing the gaskets EVERY time if it is not needed. Anyone? thanks, jm fermenter- MoreBeer Holiday Ale (did this one last year and it was a big hit)--on deck-MB English Pale--MB American Ale (this is a really good beer, my everyday go-to beer) and MB American Amber
