ULTRA GUARD

  • Base Oil Technology: Natural ester FRHF – FM Approved
  • Viscosity Range: ISO 46-60
  • Viscosity Index: 185-209

AMSOIL Industrial ULTRA GUARD Fire-Resistant Hydraulic Fluid is an FM approved product formulated with natural esters to provide outstanding performance in hydraulic systems that require a fire-resistant fluid. It is formulated to be difficult to ignite and will not propogate a flame from an ignition source; however, like all fire-resistant fluids, it is not fireproof and will still ignite and burn under specific conditions

  • Engineered polyolesters provide superior shear and thermal stability, resist sludge buildup and help maintain a clean system.
  • Oil-based formula removes vapor pressure concerns.
  • Readily biodegradable, making it a great choice where a leak or spill could release into the environment.
  • Excellent lubrication properties deliver high energy efficiency and long pump life. 
  • FM approval can reduce insurance costs in high-flame, high-heat operations.
  • Unique additive package supports long seal life.
  • Low-odor formulation for a more desirable working environment
