Our selection of fixed stem tubes are a great way to eliminate the need for a removable downstem and thus provide a simpler, less-hassle design. Essentially, with a fixed stem tube, the downstem is an integral component of the tube itself. This of course means you never have to worry about what size or type of joint needed, plus you don't have to worry about breaking your downstem ever again! Browse the best selection of thick, quality fixed stem tubes below! If you have any questions about the fixed stem tubes or any glass pieces offered at Thick Ass Glass, please feel free to contact us!
