I did unzip the wing to take a look at the bladder but I didn't try to disassemble it. The purge valve unscrews easily but your right that the elbow looks different and is on tight. I can't turn it by hand.Only thing I have noticed is the elbow doesn't seen to be adjustable... and very tight.
Haven't got out the channel locks yet.
But it appears to sandwich the bladder.
I have disassembled wings before and the elbow is usually only hand tight and has a rubber washer (for lack of a better term) that seals the flange and the elbow. There are special tools needed to separate the flange from the bladder. However, I have only worked on wings that used urethane bladders I am not sure if wings using nylon bladders are assembled differently.
Let me know your results.
