So i have just bought this bong: Black Leaf Glass Bong - Golden Dragon Series (Ice Bubble) - Online Shop This Diffuser: Weed Star Diffuser - 18.8 - Online Shop And this Pre Cooler: Molino Pre-coolers – Hurricane - Online Shop Being a big bong noob i didnt realise that all the parts wouldnt be compatible with the bong/eachother until they had all arrived and i tried putting it together (the pre cooler was only a 14.5mm joint but the female diffuser joint was 18mm). After a few moments desperation i tried to think of what i could use to make the pre cooler fit the diffuser (buying an 18mm to 14mm diffuser was out of the question as they are at least £40) and after a few moments i took out my Hookah, got the hose grommet and stuck it on the end of the pre cooler and now it fits the diffuser perfectly!! Heres the grommet: High-Life Hose Grommet - Online Shop Just thought this would be useful for other noobs making the same mistake of buying incompatible parts.
I already said that a 14.5mm to 18mm diffuser would cost like £40. Why spend £40 on a reducer when you can spend £2 or a hookah hose grommet.
A reducer is just a little glass piece that reduces the joint size and is not a whole other diffuser. They're like ten bucks.
I just bought a wrong size a/c a couple days ago I already shipped it back...but yeah I didn't get an adapter because I like the airflow from the 18.8, i think if i got the adapter I wouldn't like it, but I duno..
get a reducer for 10 bucks. and to itzbutters, the airflow change is like completely negligible. i don't see any at all.
i bought my gf that same tube a while ago. only today did i give her my mgw downstem. if u got a diffused downstem its so much easier to pull that the chugging stock downstem. i bought a fully 18mm diffuser for my mgw and the difference is noticable. the pull was much easier. if you can keep 18mm all the way throught, its a fun tube.
