Default Does PTFE react with Gasoline

Just curious PTFE + gasoline. I see PTFE seals are used in gas fittings and conditions with corrosive materials, so I"m assuming it's OK??

PTFE is pretty inert - it should be unreactive with gasoline.

Handy guide to chemical resistance of substances:

http://www.coleparmer.com/Chemical-Resistance

PTFE is not 100% resistant to gasoline, naptha, fuel oils, rated "B" by that database, and there are 3 chemicals that attack it severely.

As a disclaimer, I just wanted to add that the conditions (temperature, pressure, mechanical stresses) may all influence the compatibility for your application.
