Standard Carboy Cap - 3/5/6/6.5 gallon glass carboys
Nice idea sorta works. not a great fit on my 5 gallon glass carboy. As was stated in aother review.
Works great 👍
I used these carboy caps on my 6.5 gal glass carboys for bulk storage of wine. They fit perfectly & stay tight helping minimize contaminants from excessive contact with air. In addition, my stainless racking tube fits perfectly in the larger of the 2 ports. Going forward, every carboy I order will also have a cap included with the order.
These would be great if they sealed the carboy. I have another one of these from a different vendor that works great. I wanted to use them for CO2 transfer but they don’t seal around the glass. NB did give me a refund, so customer service was excellent.
Despite what the description says, this cap works good on plastic carboys and poorly on glass carboys.
The taller slim port is too far over to be used by a temp sensor as the sensor is blocked by the thick glass opening. That port is too small for a air lock.
