First pic, smaller one is original, other pics are the Amazon.Would you be kind enough to share the following?
1. Which is the original o-ring in the picture above?
2. In your opinion the o-ring size (345) correct?
3. Can you tell if the original is significantly softer than the replacement you bought from Amazon (70 durometer)?

I really can’t say for sure since my uptime rings are old, it’s very close but the replacement seem to be to large and slightly thicker. They also seem to be the same hardness.
