Does anyone have a suggestion for a good blowoff assembly that will actually FIT the BUBBLER plastic carboys? I bought one from NB but it really doesnt fit. The bung sinks in, making it extremely difficult to remove and the tubing doesnt leave a good seal.
Is there any harm with the tubing not making a good seal with the orifice of the bung?
I learned the hard way with my first batch…and a pretty vigorous fermentation that left an awesome sticky mess while using an airlock. 
I use the 3-piece airlocks and take the bubbler piece and the lid off. Then slip a 1/2" ID hose over the vertical piece in the airlock and add some water to seal it good. Put the other end in a bucket of water.
Make a mark on your rubber stopper where it looks to fit inside the neck. Then go to the hardware store and match up some tubing like on Lustreking’s site.
Or, just take the bottle down there. They may look at you weird, but who cares.

Crap they stole my idea I’ve been doing it that way for years.
This is what I do but I think I used some hose that might have been a bit too small. I can’t get it off and pulling on it just does the “Chinese finger trap” effect and just makes the grip tighter. So that airlock has become my permanent blow-off assembly 
Good thing they are so cheap
You also have to cut off the cross tees on the bottom end or it will plug up.
Good suggestions! A resourceful bunch, cheers!
Looking forward to less mess and hassle for my next batch which will be the milk chocolate stout. Sounds amazing!
