Standard Carboy Cap - 3/5/6/6.5 gallon glass carboys

Perfect carboy cap

These carboy caps fit perfectly, giving a nice tight seal. The additional port allows me to degass my mead without having to swap out caps, keeping oxygen out of the carboy during the process.

Great quality & Fast Shipping!

I’ve never had a bad recipe kit or product from northern brewer. Their customer service is great too.

Works great

I modified mine to be able to run a blow off tube or airlock and a thermowell for my temp control system at the same time.
