Stainless steel quick disconnects (QDs) are designed for higher pressure than us car guys will be using but will hold up much better to corrosion. Also, it looks much better and really doesn't cost much more than their brass versions. This ⅜” Female QD Coupler allows you to connect an aftermarket sprayer to a ⅜” high-pressure hose.
