I decided to try my hand at working heavy wall glass tubing. Here is my latest glass Toasty Tube. It is 12mm (1/2" = 12.7mm) Borosilicate w/ 2.2mm thick wall. One end has been enlarged to accept the Toasty Tip. The glass is 3.5" long. It is very heavy duty. It should take quite a bit to break this tube.
It cools the vapor so it is hard to tell you are getting any. Care should be taken with the first hit. It is easy to get too much.
The price will be the same as the poly tubes.
I also ordered some 13mm Borosilicate tubing to try.
I learned that Ed makes his vapor tube tips with 9/32" brass tubing. I just happened to have some in my shop so I decided to try making a Zap tip for my Toasty Tubes. They thread on and hold the screen exactly the same way as my 5/16" stainless steel tips. This one has a high temp silicone o-ring to provide a seal and control the depth of insertion to the heat sink tube.
The price of the Toasty Tubes will be the same with the 9/32" brass tips as with the 5/16" stainless tips.
The 9/32" brass tips will also work with the new glass Toasty Tubes.
bioguggernaut - Very cool discovery with the 14mm male joint. Your stainless and silicon band from your broken tube will fit into the new glass tubes.
Edit - The 9/32" brass tips will fit a Zap. The 5/16" stainless tips will fit a Toasty Top.
Stay Toasty
