Hello people of GrassCity, this is my first post and I need some help. So I am buying a new bong with a joint size of 29.2 mm, and I want to buy a precooler/adapter for it that will allow me to use an attachment I have that is only 18.8 mm. So the pre-cooler I found that I think will work says it is "Joint Size: 18.8 mm > 29.2 mm" and so based on those specifications, will the pre cooler fit into my bong with a joint size of 29.2 mm? You can find the precooler here http://www.grasscity.com/us_en/ws-29-2-4-arm-diffu… So what do you think guys? If i buy the 18.8mm > 29.2mm precooler will it fit into my bong with a joint size of 29.2 mm? My attachment's joint size = 18.8mm The precooler/adapter's joint size = 18.8mm > 29.2mm The bong has a joint size of 29.2 mm Will they all be bake to fit into each other? Thanks a lot guys, I just wanted to make sure i didn't buy the wrong things.
Pics of the bong would help. The joint on your bong is 29, does it go from 29 to 18 for your bowl? The a/c you showed has an 18mm joint that fits into your piece. The tree perc is removable and it 29 to 18. Sorry if I confused you.
