Any body know why Pro Design's kit has two brown orings for the domes while the others come will all black orings.

 

I figuer that Pro Design's kit has 2 viton or high temp orings while the others just use a regular o ring.

Probably Viton. I don't think regular O-rings will work on the domes. Pure Silicon will work in a pinch. Viton works good

The way I understand it:

 

The brown Viton is under license of Dupont who developed Viton but whose patent has expired. Other companies make Viton but can't make it in the brown color. My dome orings are Viton.
