I would like to hear from the Community on this question please. Which do you prefer? BUNA-N vs Viton based gaskets. Why do you feel the way you do? I Have purchased two different sets of gaskets because I cannot find definitive evidence as to which is best. BUNA-N vs Viton both seem to get high praise but for different reasons. It seems to boil down to personal choice and experience. I will run each type as a set and see which does best. I chose to use all Viton for my in-line filter stack. The creation & scaling of the filter stack I will raise in another post. Thanks again for your help.
