Trans cooler line o ring size?

Anyone know what size they are? I believe mine are toast.

Well after a ton or research and tearing it apart. The o ring is inside this threaded adapter between the line and the radiator. Fyi.

You can replace the transmission cooler line adapters that thread into the radiator, most auto parts stores should have them. They include the o-ring (lube before re-installing line) and new retaining clip (shouldn't reuse).
