    If your looking for any sort of longevity with rubber o-rings. Make
    sure you get silicone ones, typically they come in red/orangeish
    color...look hard and youll find some black ones.. The typical rubber
    is a buna-n type rubber which will degrade over time, Viton is
    another good choice and youll probably have more luck finding those.
