Lapkritis,

Not sure if you are a technical guy or what, but you seem not to understand what is tensile stress or strength. The o-rings at the thru-bolts don't experience tensile stress. They are under compression. Yet, you keep telling us about tensile stress. Hope you have some accredited units in Strength of Materials Testing. Some of us here have. A guy read a technical article and suddenly becomes a guru! Research the technical definition of tensile stress in your Chemical or Mechanical Engineering Handbook.
