Transferring from carboy to keg fitting

[jturman35]

Hey guys I’m about to do my first closed transfer but was wonder what fitting is used to get from racking cane tube to keg outlet? I have a hose that slides over the poppet but seems like there would be resistance which would cause oxygen? Does this look like it would work?

What you have going on there could allow O2 in.

I use one of these...

Is that larger than the standard size for beer line? Have a barb fitting, but it’s too small for the inside of the hose.

fwiw, I also use 3/8" ID vinyl tubing right over the threaded ends of the QDs, with a tight worm clamp.
No sense dealing with 3/16" ID beer line resistance when you're racking - the only thing slowing the flow is the keg post/QD interface.
No evidence of it sucking air, probably because I do CO2-push transfers so there's positive pressure, as opposed to gravity transfers where the pressure is negative...

Cheers!

Yes, it's 3/8" diameter which is likely the same OD as your racking cane, so it should fit the tubing that you are racking thru.

In my case that is exactly correct...which was the motivation...

Cheers!
