The swivel is the female nut used in the JIC(AN)connection.

Right after they are assembled you may be able to rotate the ends to get the configuration you are after. Don't get fooled and buy the assembly lube. All you need is some 80-90w gear oil. works great and is cheap.

If you use socketless hose for higher temp applications ,ie trans lines, it is recomended that a hose clamp is used (Aeroquip brand does not require the clamp if you use their AQP stuff). The heat will allow some other brands of hose to expand just enough and blow the end off. Otherwise, the socketless connection is rock solid and impossible to disassemble without cutting the hose off.

You can use industrial hose ends and save some serious coin versus using the "pretty" hose ends you listed.
