Hey there sdrons,

I think that you are miss understanding the temperture spec.

That spec represents it max operating temp in regards to it's physical strenght as related to it's spec of pressure capabbility.

150 degree F (or130 or 180) food grade PVC does not become non-food grade suddenly at 20, 40, 60, etc degrees over that spec. It either needs to physically melt or burn for it to give off toxins.

I currently have a dozen DBVs and abt another 10 of older hot boxes on loan to cancer and hospice patients. The cancer orginazation many years ago looked into the vaporizers and the associated whips. They felt as long as the plastic tubing was food grade they were safe.:thumbsup:

Hope this puts your mind to rest.

I've posted this on another forum, and they seemed to be very confident in the safety of 7th Floor tubing, and I've seen many other forums recommend them as "the place" to get tubing. So I thought I would come here for a second opinion. So, I'm worried. I've read that the 7th Floor tubing is food grade PVC tubing, which has low operating temperatures. Apparently food grade PVC only has an operating temperature of 150 F degrees. The other forum I posted on had the general consensus of "by Rating: 5
