I have a quite large generic full set of 0-rings and its surprising how few actually match what I'm looking for. Easy to match the diameter, its the thickness that varies and is hard to match from the set. For that reason I think you are going to have to pull them out and take a sample to an engineering supply shop. The 0-rings alone aren't even available as OEM parts, but rather are part of the pipe and o-ring as a complete 'assembly'.
