Default What size tube for airlock blowoff

Hey all,

I am going to try a couple firsts for my next batch. One will be my first time brewing a lager. Second will be my first time brewing with a carboy as my primary. The one carboy I own is a 6 gal glass one. It would probably be ok without an airlock, but I want to be careful. So, for my blowoff I plan to use my 3 piece airlock with a smaller tube. So, does anyone know what size of vinyl tube works for this application? Also, does anyone have any great ideas of how to keep the other end of the tube in a bucket?

Take a look at my picture. If this is what you are trying to do then you will need 1/2 inch inside diameter. I dont do anything fancy to keep the hose in the pitcher. It just stays in.

You could do it that way, or a 1" tube fits pretty snuggly in the neck of the carboy without an airlock.

I use a 1 gal. gatorade jug to capture my trub. I seems to help keep the hose in place.

yeah, I wanted to avoid the larger diameter tube because of it's crappy bending radius.

Yeah, that's exactly what I want to do. That's surprising that the hose doesn't need to be pinned down in some way during the blowoff. It seems like my siphon tubing goes all over the place when racking.
