Worried - Are stock DBV/7th Floor tubes safe?

[sdrons]

I've used tubing from 7th Floor for years. It's pretty much the same as every other OEM vaporizer tubing. If you think that tubing is exposed to heat close to 400 degrees

I think you misread.

I don't think it's exposed to 400 degrees. But food grade PVC only has safe working temperatures up to approx 150 degrees.

I don't think the tubings exposed to 400 degrees, but 150 degrees? It may very well be. Nowdays I normally pull the whip out of the DBV between pulls so it dont get too hot, but most of the vape users I know don't even do that. When I first got the DBV and didn't pull it out between hits, the tubing got pretty hot.

Also, try using the whip on your DBV without tubing (like a trumpet - as that's how the tubing comes in to contact with the DBV whip - since it's actually on the inside of the whip the stream of heat hits directly in to the tubing) and it can get pretty damn hot....
