This would be the case for "normal" Buna-N O-rings. It would not apply to
Viton, EPDM "normal" O-rings (g).

If you go into a hardware store and ask for an O-ring, you'll likely get
handed a Buna-N. They do petroleum oils well, but not weather and ozone.
EPDM does DOT brake fluids and resists weather/ozone etc.

Whoa- normal "O" rings? CAUTION! The rubber compounds used in many
so-called O rings is not up to the task, UV, Temperature and standard
gaseos compounds will break them down in just a few weeks.
If you cant do a test on the ring, like leave it on the cockpit seat
for a month or two, stick with a proven thing!
