Shame shame shame!  You're not supposed to split the caliper, it's
"against the rules".  :-)
 
Since it's brake fluid, I don't think it requires a special o-ring.  So
just find one that fits, soak it in brake fluid for a few days to make
sure it doesn't do anything funny, and put it all back together.  
 
If it was my caliper, if I had any doubts or concerns about the seal of
the joint, I'd coat it with Indian Head gasket shellac.
