<VV> Viton O ring life

[BobHelt at aol.com]

Dan,
Vitons are organic matter and their life is subject to the temperatures and 
 time that they are subject to. The longer the time that they see a really 
high  temperature the shorter will be their life. It's just that Vitons will 
tolerate  a higher temperature than the o-rings that Chevrolet used. Keep 
them at room  temps and they will loast 'forever". Let them see 900 deg F and 
they will be  soon gone.
Regards,
Bob Helt
