I am new to kegging. I have seen some people have a carboy topper that has 2 connections, one goes to a keg and one goes to a CO2 tank. I am looking to find one of these tops or the parts needed to make one. Basically I want to move the beer from my plastic carboy fermenter straight into the keg under pressure as I will be making a NE IPA and have read numerous times they dont like O2. Thanks for any help.
