guyt Posted June 9, 2008 Share Posted June 9, 2008 Anyone knows what the size of the trimetal stem+gromet. I want to see if I can get a different base than the one it comes with. Or what is the diameter of the base that comes with the trimetal? Link to comment Share on other sites More sharing options...

Scoop Posted June 9, 2008 Share Posted June 9, 2008 (edited) the original vase km uses will have a 30 grommet. Edited June 9, 2008 by Scoop Link to comment Share on other sites More sharing options...
vaypourus Posted June 9, 2008 Share Posted June 9, 2008 The size 26 grommet will fit, but you will have to file it down a bit to make it fit a vase in the 1 3/4" range.The stock KM vase size is approx. 2", which is a size 30 gasket. Keep in mind though that the main difference between a 26 - 30 size gaskets is the thickness of the gasket walls. The ID is also a little different, but not a whole lot. I had to wrap my Tri-metal stem with a bunch of electrical tape to get the size 30 gasket to seal well.Looking at this chart, you can see the difference between the medium and large gasket is the wall thickness, while the ID is the same.http://hookahcompany.com/standard_rubber_vase_308_prd1.htm Link to comment Share on other sites More sharing options...
