srb o-rings don't get compressed axially. that's not how they seal. That point is moot anyways as the shelf life of the srbs is more directly related to the j-leg seal, basically how springy it is:
“Field Joint J-leg function and proper contact is the primary reason we have the 12 month stack life requirement,” Anderson said in an email. “The J-leg is a redundant sealing feature in the motor field joint molded into the insulation that depends on contact with the adjacent segment to create a seal when pressurized.”
