Pushing out the airlocks + bungs

Hey,

i keep having a consistent problem where my bungs get pushed out – this time it’s during secondary/late primary, where there’s not enough activity to warrant a blow off tube, but the bung is just not sitting deep.

any tips to keep that chap in there?

thanks!

Wipe it with vodka and let it dry before inserting.

thanks!

I have some old ones that are really misshapen from years of use and it seems those don’t fit properly anymore so I’ve replaced them

so blowing :shock: into a carboy doesn’t introduce mouth-cooties into your beer when using as instructed?

sometimes we are a little to paranoid. I don’t use water in my racking cane when I siphon either. 8)

If you are paranoid, the filter as Shadetree mentioned is an option.

I’m not paranoid…who :wink:

:cheers:

I just duct tape mine down when they wont stick. cut a piece of duct tape lengthwise, and tape across the top of the bung, beside the airlock, down to the glass on both sides. after a few weeks duct taped down, they seem to stick without it.

and like baratone brewer said. they stick better when they are dry

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

Do these caps “allow” more or less oxygen to get into a fermenter than what would be “allowed” by using a plastic pail?

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

I used those caps for a long time, liked the ability to start with a blowoff hose, then switch to an airlock. But they don’t seem to seal very well so there would be sticky leakage during primary. In truth during primary there is so much CO2 being blown out that contamination isn’t an issue. I still use mine for racking, but maybe I’ll give the “water in the racking cane/hose” method a try, sounds like an awesome trick.

I’m curious about this research on O2 permeability. At your convenience, would you provide a link? Thanks.
