What durometer rating are the Vulcan o-rings?

No, this list is from another forum. I’m not able to post the list here but here are screen shots of the entire list. 


2) 3) 4) & 5) are all 75 durometer Viton. (I don’t believe this was used from factory but a better choice).

9) is a 90 durometer Buna (again, 90D may not have been used by factory but a better choice).

All the others appear to be 70 durometer Buna. (70D was more than likely used by the factory for all o’ring).
