Oring leaking(Brake Switch)

[TrboHead]

What type of Oring should I use? Black, Green, AC orings?
I've replaced the orings twice so far in the past years but keep having a problem with my Brake Switch Oring leaking. The switch is ok but the oring is loosing it's form due to the corrosiveness of Brake Fluid I think. Do they make an oring that will work with Brake Fluid better?

mine did the same

I just added a second o-ring, no more leak. That was over a year ago. HTH
