mercury in gas pressure regulators?

Do older gas pressure regulators leading to an individual gas appliance (gas fireplace, range, etc.) ever contain mercury? I've read that older gas regulators leading into a home sometimes contain mercury, and would like to know if the pressure regulators for a single appliance can as well. (The specific context I'm interested in involves a gas fireplace connected to a very old-looking pressure regulator.)
Here are the articles I've seen that discuss mercury pressure regulators:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1480493/
https://www.epa.gov/sites/production...ar_it_down.pdf

Thank you for any thoughts!

Welcome to the forums.

I know those bog old monster gas company regulators had mercury in them but I've never seen mercury in an individual appliance regulator. It is possible but extremely rare.

If you have one you think may be an issue.... post a picture of it. It should have specs on it..... post them too.
The model of the appliance it's on could be helpful.

Thank you for sharing your insights on this. After looking over the regulator more closely, I don't think it's an issue. Thanks so much for your help!
