I ordered a bunch of O-rings from a website. I purchased 90 duro and 70 duro versions of the same type.
I was under the impression that the higher the number the better, however, I can't remember where, but someone said in a forum not to use 90 duro all the time (something to do with pressure and elasticity). I am replacing all my o-rings so I was wondering if a) what I read was the correct and b) if the following image is accurate in terms of what O-ring duro I should use per application
To me it seems as though all high pressure applications are 90 duro, and low pressure are 70. is this an accurate assessment?
