I know it's an old thread... just for fun! I was going to buy some of the 1" tubing for a blowoff tube - but I just didn't need 10' of it!
So, my cheap overcame my lazy and I MacGyvered a solution - I have an extra Big Mouth Bubbler lid and spigot. Put one of the gaskets on the spigot with the taper pointing away from the spigot (this is important). Put the spigot into the top/outside opening of the lid and carefully line up the gasket so there aren't any gaps between the gasket and the lid. Then, attach the nut to the spigot on the other side - get it tight enough to seal, but don't crank it down so far it warps the gasket. Don't use the second gasket on this side, you won't be able to get the nut on the threads. Since it seals on the top side, this is OK.
Works like a charm and I can use tubing I already have to connect the fermenter to the jug of sanitizer.
