how to calculate the friction force due to o-ring compression
(OP)
I am trying to calculate the friction force due to a sliding o-ring. In this case, the o-ring has compression from the slider and also has contact with the side-wall of the groove. I can only find the calculation when there is no contact with sidewall. Please give me your 2 cents.

As far as any additional squeeze (and increased friction) occurring due to the deformation of the O-ring, you are now in the realm where you'll have to just make some assumptions, and go test. The amount of deformation of the ring will depend on the compound, pressure differential, temperature, fluids used, friction developed (note the recursion here), velocity of travel, etc. etc. etc. The Parker handbook reference shows a little bit of data, but it's pretty limited, and not much use if you aren't using the specific compounds they show data for. Good luck.
