If what you are selling is too complicated to represent with color coding, you need to graduate to an alphanumeric system of some sort. Here Alphabetics alone are used to merchandise Valve Stems and compatable O-rings. Look close to see that the coding is intermittent … for example there is no “D” offering. Maybe such a size oar configuration does not exist? Or maybe “D” looks too much like “O” and causes confusion in the code. Commetnt if you are a Valve Stem expert. Meanwhile CLICK the gallery for other views of a system to simplify and sell Valve Stem selections.
