I m having no luck finding silicone ones locally and shipping to my part of the world sucks, Ive got every buna size available to me. Will they work or am I just asking for trouble?
I found a nice guide here...O-Ring Online Ordering
I have Viton, they are working for me, but it looks like the bunas would be ok.
