Sealing ring used for flange connection sealing. It only states durometer65, but it doesn’t specify what the unit is or what kind of hardness it refers to. I checked online, and rubber hardness testers can measure either Shore hardness or Durometer hardness. What exactly is the hardness of his hardness? Is the seal ring hardness in the default unit?

What the original poster is saying isn’t quite clear, but Shaw Brothers and Xiao Brothers seem to refer to the same thing.

Hardness is measured using an ASTM-D2240 hardness tester and expressed in durometer A units
