What size hose is this flange fitting meant to work with, and what's the connection type on the other end?

The hose end is a -16 dash size, which corresponds to a 1-inch hose. The flanged end is a 1-inch connection, and the opposite end accommodates a line, hose, or tube. So you've got a flanged face on one side and a flexible hose or tube connection on the other, which is pretty common for routing hydraulic lines to CAT equipment ports.
