UPDATE Quick disconnect fittings

It looks like I installed my quick disconnect fittings in 2007? LINK Today I had a problem with the female stainless side (I assume SS the outside is not rusted.)…. The internals of the fitting is messed up. It was also connected to a brass male fitting which was rusted.  I am not sure if SS on brass makes a difference?

I did remove all the fittings except for this one the other day. 🙂 So only one so far is pretty good.
