I wonder if the (450 degree f) FEP-SIL might be good enough for
the coolent O-rings but use the high
temp for the rotor side seal O-rings........If the coolent seals ever see
even
450 degrees the aluminum rotor hsgs will probably start to crush !!
"Opinions"
I have to admit that I've been wondering exactly what you guys are
trying to achieve with these TES O-rings. The inner ring seems
to be a reasonable precaution, though not necessary by any stretch of the
imagination. The outer ring is just never going to see these temps unless
your engine is on fire.
The only reason I can see for wanting the TES O-rings on the outer
seal is for re-use. From what I've heard, it sounds like you can
possibly re-use the TES ring if it's in good shape. I plan to have
several iterations of single rotor parts, and it would be nice to be able to do
that if possible.
I sure hope these guys are taking notes, so they can know what
works for a rotary once you guys figure it out.
Cheers,
Rusty (working on the next RV-3
intake)
