I just started fermenting in a keg using a heated and stretched carboy cap over the keg opening. Let me tell you, transfering under pressure IS THE BOMB! (and not meaning the keg is exploding
) I just purchased a 1/4" barb to 1/4" female NPT and connected that to a 1/4" male flare fitting and my CO2
line's female flare fitting connects to that. The barb goes into the small carboy cap tube and of course, the stainless racking cane goes into the large carboy cap tube. Both the barb and the racking cane are secured to the carboy cap with screw clamps. The tube from the racking cane connects to a ball lock disconnect, so the whole process is under CO2
. 2 psi gets everything moving with the pressure relief valve left open during the process. I'll never rack again any other way! So easy!
My set-up is a lot cheaper that $80, so why am I still considering the tri-clamp solution? Well, the internal thermowell is nice. The ability to hold the racking steady is also nice. Is it $80 worth of nice? I don't know.
