My Presta valves (on new Yamaha ebike) are a shiny silver color. Is it at all safe to conclude that they are anodized aluminum? Or do valve mfrs produce silver-plated brass valves? I'd like to get some Presta-to-Schrader adapters and leave 'em on the valves, but I know that attaching the dissimilar metals aluminum and brass together would cause galvanic corrosion (unless a preventive coating is present). I can buy adapters made of either brass or aluminum, so I'm debating which type to get. Maybe the shiny silver I'm seeing is enough to prevent corrosion, though. What say you all?
Why this is on my radar: I run TST external tpms sensors on my vehicle's tire valves. TST uses brass. One time the tire store used aluminum valve stems instead of the usual chrome-plated steel, and the sensor welded itself onto the valve.
