can ethylene propylene O ring material used in MDEA pumps at temperature range of 85~95 and what is the best choice?

RE: O ring for lean amine pump seal

EPR is good for amine. But, if you may have any hydrocarbon carryover, they won't work very well. We tend to have this problem. So, we often end up using Kalrez in Amine. It is expensive, but works well for us.
