Basically my old bowl and downstem broke. I have a Black Leaf Golden Dragon Series Bong, and the measurements are Bong + Downtube Male Joint: 18.8 Bowl + Downtube Female Joint: 14.5 Im not to sure about what size to get for the downstem or the bowl. This part always confuses me, help please!
You have an 18/14 reducing downstem. The female joint on the bong is 18mm. The downstem is 18/14. The slide is 14.
