Looking at the specs, I think mine is actually a basic bubbler. It is slightly taller and 14mm.
all the joints are female.

The mouthpiece is 14mm as well.
I also got the L-bend mouthpiece which I prefer in every scenario. Provides better view of bubbler so you can see what you are getting, and puts you further from the nail if using oil.

I recently bought a SB beaker bottom tube to replace my Roor. I went for one that
had a very small logo. It hits like a beast.
