O rings swelling up

[anon4]

Yes its spamon4 making yet another thread sorry. My diy peach and pineapple juice is making my crown top fill o rings swell up and fall out the top cap. Suspect it's the same reaction that ripe banana and pineapple jam up syringes with but it's only happening with juice containing the pineapple and it's getting frustrating, what is in that stuff? Left it for a good breathe before capping and steeping but my o ring fell out again and won't go back in. Help!

Not sure how to stop this happening but if you wash the o-ring in hot water it will probably go back to normal when it has dried.
I had the same problem with inewara banana on my Tfv4

Can't remember which concentrate I was using the other day but it did in 4 of my syringes that even when I had washed and dried them I had to bin them as the stopper no longer fit and worked, right pain but cheap enough to order more, just wish I'd written down what concentrate it was to stop me doing it again and use my glass syringes instead for it

I've been mixing by weight and it's a lot less hassle tbh
