Rusty,
   Chuck Dunlap is currently flying with TES O-rings supplied to him
by Paul Lamar........ These are Creavey seals of the sizes determined
by Paul L.......I failed to ask Chuck the flying hours on these seals.....
Chuck jump in here if you are listening !! I do know that the flying
conditions in Arizonia  where he lives put a strain on both coolent
and oil cooling systems and their respective seals.......If there are
others currently flying these seals in the rotors I am not aware of
who they are !!

Hi Kelly,
 
Thanks for posting the final results of your quest.  This will be good info to stash away.  If nothing else, these are quite a bit cheaper than the stock rings. 
 
Is anyone currently using the TES o-rings for the oil seals, and have significant time on them?
 
Cheers,
Rusty
