Are there corrosion problems with these two metals touching? I'm adding a pump to my system and trying to figure out if I need to make one of the QD sets stainless.

Should be no problem. People mix SS and brass all the time.

But there are some very good SS quick disconnects available at very good prices. Have a look at Bargain fittings cam lock style disconnects.

I use teflon tape on all the threads, so any dissimilar metal corrosion will be minimized. But brass and stainless don't seem to corrode much in contact, anyway.
