Carboy Cap- 3, 5 & 6 Gallon Carboys by Learn To Brew LLC

This does NOT replace a regular carboy stopper though. It is helpful for me in other things such as vacuum degassing and transferring to secondary carboys or bottling buckets. Someone else pointed out how it can be used to start a siphon without a special siphon device hand pump too. The seal is not that snug so you might need some vaseline to help with that.

Works perfectly with my 5 gal carboys.

fie great works good. this.

I've struggles with auto-siphons and primer devices for a long time before discovering this little beauty. Just thread your racking cane through the center and give a stiff puff into the side inlet and presto! Your wort will be transferred quicker than you can say "I need 4 more feet of tubing." The only aside is that it will not fit on 6.5 gal carboys. You'll have to purchase a separate model to fit. When using for storage, again, just snap on with the 2 white caps in place.

Work good fit right on my car boy nice and tight like I wanted it to . All in all it did a good job pretty good quality I know it will last for years
