Hi. I've put a couple of brews in bottles and now set myself up for kegging. Ive read so much about the need to protect against oxygenisation and watched so many closed transfer videos. I have a Grainfather G30 fermenter and will be using corny kegs. Obviously I have limited (nil) expertise in using gas and the equipment/lines that come with that. But I am practising with water to make sure that on the day of transfer from fermenter to keg I am confident that I can pull it off without much bother. Here's the thing; I have two ways of doing the pressure closed transfer from fermenter to keg. 1) via the dual outlet tap in the bottom of the fermenter (applying gas pressure at the top) or using the Grainfather closed transfer kit with racking pipe at the top of the fermenter. . My problem is selecting the right fittings to connect either of those with the keg. The range of fittings that I view at the online retaliers really confuses me. The GF outlet tap takes a 12.5mm fluid tube (OD ~16) and the racking pipe at the top of the ferementer takes a 7.9mm tube (OD10.7).

What do I need in terms of fittings (reducers, barb connecters etc to get either of these into my keg via the fluid disconnect. I've added some pics. (ps I live rurally and about 5 hours from a local homebrew suppy retailer, so need to use the online option).

Thanks in anticipation. Bruce

I'm not familiar with that fernenter. Is it built for pressure? Ball lock QDs?

From your description, no and no? And you'd be applying very low pressure?

Is it sitting on the floor or elevated?

With 1/2" ID tubing and a gravity transfer, I've removed the post hardware from the keg and clamped the tube directly to the dip tube and post threads. You can get barb reducers, if you want to reduce to a QD.
 
You could change out the fitting on your drain valve.. I found this, (though currently sold out) in your region:

..you can probably source the parts, so it might be worth looking at.
And like @mashdar asked: Is it on the floor, or elevated? If it's on the floor, you'll need your CO2 to push it from fermenter to keg, but if it's elevated you can save your CO2 and use gravity in a closed-loop; Just plug the gas post into a line to return gas to your fermenter. Here's a pic, different fermenter, same idea;

and here's another one using CO2 to push:

Hope this helps a bit.

Thanks everyone. Yes it's elevated and can take low pressure 1-2psi. But I think I'll give the syphon system a go using a barb connector on the gas disconnect as in the image from brokencrow just need to purchase the barbed gas disconnect...I assume that are all the same size barb? I'll look into changing the fitting on the dual valve at the bottom of the fermenter as well... just so I have another option.
Thanks again for your prompt replies everyone
