This was a tough decision we had to make. We chose black because of its superior properties over brown or green material. The tests showed that Black Viton compared to Green or Brown Viton, with all parameters constant except for the color, is favorable. It has higher strength, better stability and better elastic properties originally (brand new), and also after exposure to extreme situations that cause material fatigue. It also possesses higher resistance to surface damage.
