Another Advantage, is that the seals will have the ability to be reused WITIHIN A LIMITED/REASONABLE timespan: ie, you build a engine, test it on the dyno and need to tear it down again. They are not designed to be driven 100K, torn down and reused.
sorry for all the questions. just trying to grasp the whole concept.

A. We haven't had a set in an engine for 100K to test and see if they are still serviceable.
B. Any spring after a certain number of Cycles( whether mechanical or thermal Cycles ) will take a "set" and not provide the same reaction force as in new.
C. Majority of the Cost is due to Manufacturing in low Volume.
Even in Bulk orders these are an expensive product to produce. I will be posting pictures of the Manufacturing steps as they occur. These are essentially hand made to order

PS I don't mind the questions at all, keep them coming. If I don't know/have the correct answer it will be asked of the design engineer
I talk with them every couple of days, they enjoy spending my $$$

ok, cool.
the reason i was asking about reusing it was because the only other hard seals that are currently available for the engine are friction parts. the coolant seal is stationary. so in theory, if this type of seal material is "unaffected" by heat and just the helical spring would need to be replaced. then it really would be worth the money spent. given the helical spring is pricewise worthy of the upgrade.
also theoratically speaking this seal setup will be able to sustain higher temps, so engine rebuilds due to coolant o ring failure will be few and far between.(i dont recall if u stated that already.lol)
has this material been used for similar applications?
PS i might be way off on some of this comments so please forgive me if i am....

Due to the construction of the seal, the spring is not replaceable, it is an integral part of the design.
Lets see: Thi seal was used in a isotropic gas seperation vessel I designed that cycled from -40ºF to over 400ºF in a 15 minute cycle, seven days a week/ 365 days a year. Also used to seal Nuclear Reactor Vessel Heads. IRL and F1 engine head O-rings are made by the same company. Also Tractor pullers ( who are running in excess of 150# of Boost) are also utilizing the same technology.
I am trying to eliminate Coolant Seal Failure in the Rotary, This product will not help in the case of groove blow-out. But we will be testing an iron that has a blown out groove (Just to see what happens
This is not a half-assed project, I am working with the PREMIER seal manufacturer in the world on this. I will have a set of these in my engines even if they don't become a commercial success.
