Welding gas bottle knob indicator

This is clever. If you twist it one way, to open your welding gas bottle, it opens the windows turning red, and when you close the bottle, it goes back to yellow. Not sure I have an issue, but definitely have left gas on before...

Good for propane too. Zero affiliation. Just thought it was neat.

I'll give one a rip.

I approve. they're thick and have a nice click on each end of rotation so it can't just jiggle and read incorrectly. ordering 2 more for other rigs.

Hell yeah! Good enough for me.

We use these at a community maker space I volunteer at — they are great as a quick visual to ensure valves are closed especially for tanks that may sit hooked up, but unused, for long periods of time.
