So, what I plan on doing is to buy them from an aftermarket company made from a different material. So far, I have narrowed it down to three materials: Viton N75D or Buna-N 70D for most of the o rings, and Urethane 70D for the o ring inside the reservoir, since it has to survive a lot of abrasion. I would use Viton over Buna-N, since it is rated better for a compression-set situation, however I heard that Viton on 1:1 shocks tends to leak at lower temperatures.
Could someone who has more knowledge about this please tell me which material I should probably go with, and also correct me if I’m wrong about any of this? Also, even if the Viton material does leak on 1:1 shocks, could it still work on rc shocks without issues?
Also, I go into more detail about this on my build thread found here:
