The current Jupiter 582 has stainless steel pistons. I believe they were nickel before they changed to stainless steel, but I'm not sure. Anyone knows?
And when did they change to stainless steel?

They changed to stainless about 6 years ago. the monel/ nickel material they were using was tarnishig ang causing the valves to stick

Are the nickel valves from Jupiter bad enough to avoid having one with nickel valves?

Is there a reliable way to way to determain visually whether the valves are nickel or stainless steel?
