Food Grade Fire Resistant Hydraulic Lubricant Biodegradable ISO 32-68

Fire Resistant Hydraulic Fluid Biodegradable

Series SL-FRHF-HF is formulated to offer superior fire resistance and enhanced lubrication and protection. Unlike most water soluble glycol based formulation, Series SL-FRHF-FG is far easier to maintain, has an exceptionally long fluid life, and, offers superior pump protection. It is non-toxic and non-hazardous, and 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. The hydraulic fluid is biodegradable, NON-Toxic, NON-hazardous and gives an extra level of protection and operational efficiency in high and low temperature hydraulic applications. They meet USDA H-1 requirements for lubricants with incidental food contact (FDA 21 CFR 178.3570).
