Thanks for the info guys, I now have a few more variables to play with. The hardness of the o-ring is 70-75 so it's somewhat hard unfortunately and I might have to get another type. I couldn't find the Young Modulus, but I think it should be available somewhere online, the rubber I'm using is Bunna-N/Nitrile. From McMaster it's item 9679K21.

With this additional info it seems that one of my mistakes was not making the channel wide enough, that coupled with the durometer being 70-75 and 80% depth channel maybe less isn't allowing for the sort of compression that I need.
