O Ring Gasket (between pedal and pod)

I am going to be moving my original version Vectors (dual) from an older spin type bike to a newer one. The O Ring Gasket that lives between the pod and the pedal is basically not salvageable on one pedal. I assume that, given that I will never be outdoors with this pedal, that I should still try and find a replacement for that O ring. Is that right? It is interesting that this O-ring does not show up in the exploded picture in the manual. I tried to show the location below. 

Thanks.
