LUBOLD8431:Huh, could you please let me know what these mods are? Because as a service technician, I would really like to know what kinds of mods you are making to HP seats and/or orings to make them deal with HP better. AS far as I know, there are no such things. Certain manufacturers have changed their seat material over the years to make it more reliable when using HP.
I just dont know what you may be referring to...
I am told that higher durometer ratings are used to account for higher pressures. Makes sense to me. I'm not making the mods, so I do not know. Apparantly (deducing from your comments), there are reg techs that make claims that are just not so. Can you give me some confidence that this is bunk and that it's not just something that you have not learned (I'd grant that this is not a maufactures suggestion - so I don't suspect that it's a training issue). Durometer on o-rings serve to account for the required higher pressures to distort the oring to seal, but not to the point where the o-ring "blows" (and it's wearablity). Would you agree or disagree with that statement?
