Sublimator Glass Tubes are an all Glass tube for your Sublimator.  Made in Canada with the highest quality 5mm thick glass as possible.  Replace the plastic Sublimator tube with these all Glass tubes.  The Sublimator Glass Tubes include two sealing o-rings in the bottom end of the tube to hold it steady in the Sublimator base and one o-ring in the top end of the tube for a tight seal with the cap. Finished with real Platinum "Sublimator Beyond Vaporisation" logo and the black stylized "S Monkey" logo which really shine when the tubes milk up.
