My oxygenation rig used* a polymer hose between the sterile filter and the sinter and I autoclaved it before every use with no ill effects. Just don't use plasticised PVC or polythene tubing and you should be OK.Another benefit of the wand is ease of sanitisation. You can dunk the whole thing into the wort during the last 5min to sanitise, whereas with a bit of gas line / poly tubing I assume you can't subject it to such temps and have to dunk in sanitiser instead.
Re the swirling thing: it is probably unnecessary. Research has shown that you need about 6 metres of fluid depth for all the O2 released from a standard sinter to go into solution. If it's not going into solution it will create a bubble train which will mix the wort for you: rousing a tank with gas is a standard way of mixing.
* I no longer use a standard oxygenation rig as I'm working on a substitute. Will report details in a few months.
