Food Grade Rust & Oxidation Oils ashless, food-grade lubricants that combine premium quality base oils specially developed for use with machinery handling food. Some hydraulic systems, rotary air compressors, lightly to moderately-loaded enclosed gear drives, and various other machinery in food and beverage plants require specific oils that limit the danger should these lubricants come in contact with the food item being produced. Oils listed here are registered by NSF International as H1 lubricants for use where incidental food contact may occur. Additionally, these oils may be employed as an H2 lubricant for use in applications where there is no chance for incidental food contact. Food Grade Rust & Oxidation Oil also meets Canadian Food Inspection Agency requirements specifically for use in federally registered food plants - these oils are also certified Kosher and Pareve.
Food Grade R&O oils that are labeled ISO VG 32 have a midpoint kinematic viscosity of 32 cSt (mm2/s).
