HELP: Need Facts About Apex Seals
 

Is it true that apex seals from rotaryaviation.com wear out rotor housings faster than apex seals from let's say atkinsrotary.com? Does anyone know the comparison between rotaryaviation.com's apex seals, atkinsrotary.com's apex seals and good old OEM apex seals? Thanks a bunch beforehand for the help guys....

Basically, like this:

Soft - Atkins
Normal - OEM
Hard - Rotary Aviation

Rotor housing will wear no matter what, its the nature of the game. However, harder seals cause increased wear over softer seals (as one would expect).

just like piston rings:

Cast iron
Steel
Chrome Molly

Harder material will give better seal but wear faster due to their hardness.

aviation rebuilds
 

I would suspect that this has something to do with aviation motors being rebuilt after a set number of hours.

This is slightly different than with cars. eg. rebuild after it overheats and leaves you stranded.

Airplanes stranded due to engine failure usually don't have the opportunity for a rebuild.

jkstill...nice humor ... you are correct though, there's mandatory inspection every certain # of hours (depends on the type of craft)...maybe we should start using something similar for our cars eh?

thanks a bunch everyone for the help, and good luck with your sevens....
