Miles Fg Hydro Fr ISO 46 - non-toxic and non-hazardous, and it gives an extra level of protection and operational efficiency in high- and low-temperature hydraulic applications. Miles Fg Hydro Fr meets H1 requirements for lubricants with incidental food contact (FDA 21 CFR 178.3570). Its exceptional oxidative stability, corrosion resistance and anti-wear properties make it particularly well-suited for applications where other fire-resistant fluid technologies are restricted. TYPICAL PROPERTIES: ISO Grade 46; NSF H1 Registration Number 152884; Viscosity cSt @ 40°C (D445)-45.1, Oxidation Stability (D943)-10000+, Color (D1500)-
