Sealing issues at the glass sight glasses of the vacuum tower and reactor

Thread Content

I have a question regarding the sealing issues at the glass sight glasses of vacuum distillation towers or reactors What gasket should be used? At a temperature of around 250 degrees, I used ordinary asbestos sheet gaskets wrapped with tape; there is one piece of tempered glass on each side, and air leakage occurs frequently, which affects the vacuum level. The liquid level sight glass of the special tower bottom is often submerged in liquid, making sealing even more difficult.

Try PTFE gaskets. They are resistant to high temperatures as well as corrosion.
