I need to replace a leaking progressive gas tap from a Cooktop. The manufacturer doesn't provide spare parts anymore. I found many alternative options. Some look exactly like the defective tap. But I'm not sure because there are lots of codes on both sides, also there seems to be a color code too.
I noticed in one side there is always this PMAX and a number and an arrow and another number. In the opposite side there is this equal and a letter and 3 other numbers.
