Glass Tube for Davinci,ITDQ Ascent Glass Tube,DHrying Tube Straight

Not a perfect match to the original but it fits and it works well. I like the rubber attachment to plug the mouthpiece a lot, helps with scent and keeps vapor in the pipe. Also for what it’s worth, came very very quickly. This is also the cheapest replacement set I was able to find online, so I’ll take that too.

When cleaning, use a very slow, light pressure. These break easily and are best cleaned with a mini pipe cleaner and tooth pick after soaking in alcohol, ideally every 3-4 uses to avoid buildup. With more buildup, cleaning is harder and thus getting it fully clean takes way more work. The simplest thing is to rinse it out with alcohol at the end of the day after using. It's a change in routine that will save you lots of time later and be good for your health ;-)

not a perfect fit compared to original, but does the job just fine
