What size ash catcher do I need for my bong?

Discussion in 'Apprentice Marijuana Consumption' started by AlexTheGreat8, Feb 15, 2010.

  1. So I measured out the opening of the downstem to be 18mm. Does that mean from now on if I order an ash catcher I need the 18mm?
  2. *BUMP* I took a picture and labeled the parts with measurements to make things a little bit more clear.

  3. Yup, you need 18 or 18.5mm. Some places just put 18, while others put 18.5
  4. its hard to explain but theres actualy two sizes that are considered 18.8, on my gear ash catcher the downstem for it is huge its called a18.8 and the joint for the down stem is 18.8 and way smaller so watch for what your buying
