my bong was 40$ canadian, its 20" 14.5mm gong 3.5mm thick glass the slide it came with fits very well although the female joint DOES wobble a bit(doesnt affect the tightness of the seal though(and i thought it would). I also once had an 8" GonG bong i got for 20$ in a case, im sure you're aware of the kind i am talking about, those cheapies imported from china, it also has a 14.5mm slide and its slide fits mine perfectly. In fact, i once found out, that a beaker at a surplus store that was selling for 4$ had a GonG seal top, and that plug was 14.5 mm to.

Thats not to say it cant happen,i just havnt run into it, but your cases are the first ive ever heard of with this problem that the slide is a LITTLE too big for female. Keep in mind though, id tend to think that the BOTTOM of a 18.8mm slide wouldn't be much bigger than the TOP of a 14.5mm female, could this explain the phenomena possibly?

Anyway, Id email EDIT about it, they're nice guys and will prolly help you out, send you out a proper one or something.
dankus maximus Reviewed by dankus maximus on . Finally got my new bong Thank Ganja, that's rite. I finally have a new bong, i broke my last one :( I've been using my bubbler since. Okay, i ordered this bong and it should have arrived on the 22nd of december, but it didn't. Today my mum had to drive down there and pick it up coz they didn't deliver it 3 times.. The slide they gave me is way to big for the bud and my glass screen. I didn't have any other screens but luckily i've kept the slide from my old bong and it worked. There was no bubble with the water Rating: 5
