Hi Brent! You should be able to solder to brass - check with you flux supplier to get their recommendations. The flux you are using may not have enough activation to breakdown the oxides on the brass surface. On word of caution - brass (copper and zinc alloy) can undergo 'dezincification' if there is no barrier plating between the brass and your solder joint. In some use environments this becomes a latent defect. Good Luck.

We are attempting to do this and not having much luck. If anyone has done this before and has some suggestions that might help I would appreciate it thanks Brent Green
