The hose grommet is simply a rubber, plastic or silicone gasket that creates and air-tight seal between the hookah hose and stem. Here we have the seemingly unimportant hookah hose grommet, and yet without this somewhat insignificant accessory, your whole hookah operation can come crashing down.
Different sizes and materials are available depending on the size of the hose and hose port and the texture and material of the hookah parts themselves.These parts are so inexpensive, we highly recommend stocking up with these and keeping a few dozen of multiple varieties on hand to fit and fix any situation. You can even double them up and use multiple grommets if needed on large hose ports.
