Transfer case seal

My transfer case blew a seal while driving down the road at 70 mph and blew fluid ever where. It’s between the backside of the case and the retainer before the tail housing does any one know what that gasket is called?

Check the transfer case vent hose. I can't imagine the gasket popping unless there's pressure build-up in the transfer case.
