For kicks, cut it open.  I did this once with a right angle "N" 
adapter that I bought at a swapmeet, and in which I observed poor 
performance.  Inside I found the center conductor was a small 
spring!  The idea, I believe, was that the spring would naturally 
form a gentle circular arc from the center pin of one connector to 
the center pin of the other, maintaining nice spacing from the 
sidewals.  This would be fine at DC, or maybe HF, but at UHF this was 
worthless.  The spring was electrically a coil, in other words an 
inductor, which was altogether the wrong thing.  Laughable.
