Glass pipe, fittings, and couplings, is approved by
U.L. for return air plenums. Unlike PVDF,
Polypro., and other plastics, you no longer have to worry about invisible,
deadly, & toxic fumes, compromising the Safety of your
facility!
(Example: According to Material Safety
Data Sheets, PVDF emits hydrofluoric Acid
(HF) the deadly, toxic gas when exposed to a little heat. do you want this
gas in your return air plenums?)
