These caps introduce more oxygen than a bung
Also make sure you let your bung dry or secure it with tape. After you santize them they never want to stay down, piece of tape or getting it dry helps a ton.
Thoose caps work great for making a setup to transfer with c02[/quote]
Do these caps “allow” more or less oxygen to get into a fermenter than what would be “allowed” by using a plastic pail?[/quote]
depends what your doign with it I suppose. Bungs let oxygen in to. THere was a spread sheet put out just a little while back showing how much oxygen these things let in. The caps were the worst. I have noticed them with my sours to, I would get a pellicle with those thing in no time.
Using it for just a couple weeks like u bucket would be used your are probably fine
