Air Products Fluorine Regulator, used but in good physical condition. Part number E11-F-F3321. Unfortunately, I don't know the rated inlet and outlet pressures, however the inlet gauge is a 0-3000 PSI range (0-20000 kPa) and the outlet gage is 0-500 PSI (0-3500 kPa).
Label says "Fluorine Regulator - this regulator has been specially cleaned and treated with fluorine. Warning - do not destroy treated internal surface by introduction of foreign materials. Fluorine is the strongest oxidizing agent known. See specialty gas MSDS for fluorine before use."
