Whats the Joint size?

i couldn't tell you the size, but it could work on any other bong i supose if it was the same joint size

 

well... what size is the join on the mad scientist i would assume it could fit any other joint the exact same size as the mad scientist

 

looking at the picture of the bong it looks the the tube has a 18mm joint, but it comes with a bushing downstem so it uses a 14mm bowl.

not that knowing that helps lol

 

i think they just changed the descriptions but im 90% sure it said 14 joint. and i assume since the inline is made for it, both joints would be 14

^^yeah this seems right and according to EDIT the joint is 18, BUT the downstem is 14. soooo the inline must be 14 to fit the downstem

 

Assuming v2 and v3 have the same joint size, it is 18.8

 

it baffles me how they can sell that piece for 48 bucks.. and the clear one is 26
