Reply to "looking for replacement oil"

Phosphate esters belong to the HFDR category of fire resistant hydraulic fluids where as PAG (Polyakylene Glycol) belong to the HFDU category. HFDU also includes polyol esters. The issue are compatibility with seal, paints, metal, packings and hoses. Typically both the fluid manufacturer and the system manufacturer should be consulted to determine the suitability of one category of fire resistant fluid to another. As an initial, it may pay to consult another supplier that can supply a phosphate ester fluid preferably closely matched to what you are using.
