Rubber bong bowls are all bowls and downstems which are tightened with a rubber grommet. You don´t pull out the bowl while smoking but only usie your finger to cover and uncover the carb hole on the bong. Rubber grommet bowls are made as one piece so the bowl is fixed together with the downstem. It is not possible to subsitute the rubber bowl for a glass on glass bowl.
Rubber bong bowls for sale online
All our rubber bong bowls are hand blown by our crafty glassblowers of hard borosillicate Pyrex glass. We offer plenty of different designs either from pure or colored glass. Rubber bowls for bongs come in two sizes, with diameters 9mm and 14.5mm and few different lenghts. They are intended mainly for small glass bongs and some bubblers.
Spare rubber grommets for rubber bowls for bongs
The rubber grommet is included with each rubber glass bong and it is also possible to buy spare rubber grommets if needed. Once you decide to replace it or just need to put it on the bowl, we recommend to use some oil and use a screw motion to prevent breakage. From time to time it is as well good to lubricate the rubber a bit to preserve flexibility.
