Rubber Stopper- Size 2- Drilled

These were hard to find anywhere else but the way I’ve been fermenting is to use different size flip tops to hold reserve liquid after each racking. Flip top bottles were the best way to ensure minimal headspace but remembering to go and release the pressure every day would have been a huge task. Instead I use no.2 corks and a 2-piece airlock (also found on Amazon) till fermentation stops before sealing with the flip-top.

Perfect for making blown glass bottle stoppers on 10mm rod. Good quality, consistency, and service.

good product

Purchased for a counter-pressure bottle filler, did not work well. the stopper is too small.

These left a strong rubber aroma and flavor in my fermentations. I am quite certain that it was the rubber stopper because the aroma was not present after the primary fermentation (in a bucket with grommet and airlock) and only appeared after the secondary (in a carboy which I have used plenty of times without issue) and persisted through bottle conditioning. The aroma in the beer is distinct from chloro-phenols or any infection that I have ever encountered. The stoppers have a strong rubber smell to them which matches the one in my beer.

Lo compré de repuesto para el stopper que venía con la SS Brewbucket de 7 Gal, le quedó muy bien, solo no aplicar demasiada fuerza porque lo puedes tirar dentro del fermentador. El material se ve bastante bueno ya tengo 6 meses con el sin problemas.
