I am in the process of an avionics upgrade which requires the installation of the red cube. My installation requires two 1/4 inch NPT to #6 AN straight fittings. I am installing all stainless steel fittings FWF. I found the fittings on Amazon and ordered them. They arrived yesterday and I immediately noticed that they sure seemed light. I pulled the packaging out of the garbage and saw that they are stainless steel "colored" aluminum. The ad clearly states they are stainless steel. They aren't. I just wanted to give everyone a heads up,
