True, the seals are made of unobtainium : )  But it gets worse.  Will soon introduce nitrided unobtainium seals.  This is in response to the drag racing maniacs running 30+ pounds of boost with occasional detonation.  The seals still don’t break but they can be bent downward in the middle when at high temperature and detonation slams them down, bottoming them out on the spring seats.  The nitrided seals retain their strength at higher temps.
