I finally found out what the difference between red and blue AN fittings is. Red means don't touch and blue means go ahead and...
Comes from the military specs during WWII..

Red means you can put a wrench on it to stabilize it but do not turn it. (see how it is on the tubing in the photo) Blue means you turn those fittings to loosen/tighten. Saw it on one of the Powerblock shows a week or so ago.

What is the thing they are attached to? Why can't they touch it? Sorry, I am simple.

All I can tell you is what I learned when I worked with hydraulics. The fitting attached to the hose is fixed (red). You do not turn that. The attached fitting is able to be turned (blue). That is what you turn. The AN color designation just Murphyproofs it. Also, they are 37 degree flares vs. 45 for most industrial applications

I may have not totally answered your question. The red fitting is attached to the stainless steel wrapped line, That cannot be turned because it is usually swedged (crimped) to the red fitting and is not intended to swivel or turn, The line carries the fluid (hydraulic, brake, oil, etc and the red fitting is there to connect the two lines together.
The blue line has a different type of connection because the female/male fitting is designed to turn and compress the 37 degree flare fitting to the fixed 37 degree male/female fitting. Hope that explains it. If not send me a comment and I will try to clarify.
