This nifty option will change your current 9mm slide waterpipe into a 18mm glass on glass water pipe. The down stem has a diffuser on one end, and a 18mm GonG fitting on the other.

The length is measured from right below the glass on glass fitting and bubble, down to the very bottom. Make sure to measure the depth of your waterpipe using a pencil or something else long. The end of the pencil should be right above the glass. A little shorter is better than a little too long!

Turned my 16 inch ceramic beaker bong from a "old school" rubber grommet bong to a more modern glass on glass bong. This allows me to add pieces to my bong without having to buy a complete new one.
