Description

QUINTOLUBRIC 888-46 is a synthetic HFD-U (fire-resistant) hydraulic fluid based on organic esters and anti-wear additives. It delivers premium AW-level lubrication and, thanks to excellent oxidation and shear stability, suits installations where fire safety and reduced environmental impact are critical.

Benefits and unique features

  • Synthetic ester formulation – high oxidation and shear stability
  • HFD-U class – use in fire-hazard areas
  • High thermal robustness: flash point about 300 °C, fire point about 360 °C
  • Low pour point < −30 °C – reliable cold starts
  • High viscosity index – stable viscosity across temperatures
  • Excellent lubricity (FZG > 12) and low foaming
  • Reduced environmental impact, high biodegradability

Properties and applications

  • Fire-risk applications: replacement for mineral AW oils in presses and heavy-industry hydraulics
  • Environmentally sensitive sites: operation without compromising overall system performance
  • Materials compatibility: suitable with many metals; elastomers NBR/FKM/PU/PTFE – compatible; EPDM and IIR – not recommended
  • Fluid compatibility: miscible with most mineral, phosphate-ester and polyester-type fluids; not miscible with water-containing fluids
