The regulator is a Tap-Rite, came with my summit kegerator.
The bulkhead assembly is as per usual. That was on my old keggle.
I did buy the 3/8 to 1/4 adaptor that would allow you to use that bulkhead valve on your gas side if you were somehow inclined.
Other stuff is just various brass bits you can have for free including the three regulator adaptors (cga 346, cga 590) come also. You would only need them if you wanted to put this regulator on a beer gas bottle.
Story of the regulator is this: I wanted to attach the beer gas adaptor and mangled the cga340 for the co2 a bit (it still works). I got frustrated and gave up. I don't need a third co2 regulator. Apart from that this regulator is essentially unused. Should you want to replace that co2 adaptor for lack of trust, the cga 340 is ten bucks at your local welding supply or between 2 and 5 bucks online here and elsewhere:
Hope this helps someone. I think the price is quite good.
Since my acct is new here, I am felixn on ebay so you can have some feedback history. Happy to go through ebay if you pay the auction fees.
