Viton O-Rings

Viton O-Rings

Why are my orings black?

We hear this all the time.  Viton and Buna orings are black when they are made.  Viton orings are dyed to other colors. When orings are dyed the dye etches the oring, when orings are etched they are actually cutting into the life cycle of the oring. This is why we ship black viton they have been untouched by life destroying dyes.
