Stainless steel ball lock carbonation caps with 1/4″ barb. These are intended to convert 1L and 2L bottles to pressurized growlers. Fill up a 1L or 2L PET bottle with your beer. Put one of these on (purge the head space by squeezing if you want to) and then pressurize for transport. You can also use this cap to rapidly carbonate beer. Same process as for transport, just shake it up until it’s carbonated.
The last time (that I can find) that I had something like these on, they were selling for $12.80.
These are selling for $7.99 with $2.74 shipping. That figures to $10.73 Shipped.
Check them out – Here – These apparently have a few scratches on them from shipping. Check out the product description.
I have a Recirculating Draft Line Cleaning Build that I’ve used for a long time. I just purchased one of these to try out as a replacement for all the ball lock fittings, connectors and barb. If this works (which I think it will), you would just need the stainless carbonation cap connected to tubing connected to the submersible pump. This takes a lot of cost out of the build.
