I like the silicone o-rings because they’re red.As regards this issue with the material of orings I have no idea whether the viton orings pose any real risk to us, but I find it hard to imagine that George would continue to use them exclusively if they presented any significant danger. How long they last, how much swelling might they have, how well they isolate components, how much they cost, AND how well they behave when mistreated (as well as other variables) these are likely all considerations for determining what to use. Which variables are most important has to be determined by the individual making the decision.
I’m more than satisfied that each of these gaskets is worthy and adequate to the task.
Given that, I like the red ones!
The end.
