Barrier Fluid (Oil or Water not permitted)
(OP)
I need a barrier fluid for a back to back seal.
I cannot use water or an oil (mineral or synthetic)
Im considering Propylene Glycol and Propanol.
Can Propylene Glycol be used 100% i.e. not part of a 50.50 mix with water?
TIA

There are some other options. Fluorolube is another I've seen in use, awfully expensive but effective.
Could you use a gas seal instead of a wet tandem or pressurized seal in this application? Even a dry running containment seal with an inert (N2) purge might do the trick.
