QUINTOLUBRIC 888-46, synthetic HFD-U fire-resistant hydraulic fluid, ester-based, high viscosity index

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
