Product Data Sheet
Why QUINTOLUBRIC® 888-46
QUINTOLUBRIC® 888-46 is formulated as a direct replacement for anti-wear, mineral oil-based hydraulic fluids in fire-hazard environments, without a drop-off in hydraulic performance. It is FM Approved, and its synthetic ester base delivers excellent shear stability and best-in-class oxidation stability, while its readily biodegradable formulation reduces environmental impact in sensitive applications.

Compatibility
- Compatible and miscible with nearly all mineral oil, phosphate ester and polyolester-type hydraulic fluids. Not miscible or compatible with water-containing fluids — contact Quaker Houghton for conversion recommendations.
- Compatible with iron and steel alloys and most nonferrous metals and their alloys. Not compatible with lead or cadmium, and has limited compatibility with alloys containing high levels of these metals. Limited compatibility with hot-dipped or electro-galvanized surfaces; good compatibility with zinc-containing alloys.
- Compatible with multicomponent epoxy coatings. Limited compatibility with one-component (zinc-dust containing) coatings — consult the coating manufacturer or Quaker Houghton for specific recommendations.
Elastomer Compatibility
| ISO 1629 | Description | Static | Mild-Dynamic | Dynamic |
|---|---|---|---|---|
| NBR | Medium to high nitrile rubber (Buna N, >25% acrylonitrile) | C | C | C |
| FPM | Fluoroelastomer (Viton®) | C | C | C |
| CR | Neoprene | S | S | S |
| IIR | Butyl rubber | S | N | N |
| EPDM | Ethylene propylene rubber | N | N | N |
| PU | Polyurethane | C | C | C |
| PTFE | Teflon® | C | C | C |
C = Compatible. S = Satisfactory for short-term use; replacement with a fully compatible elastomer is recommended at the earliest convenience. N = Not Compatible. Static refers to trapped, non-moving seals such as O-rings in valve sub-plates and rigid, low-pressure hose connections. Mild-Dynamic includes accumulator bladders and hose linings exposed to high pressure and light flexing. Dynamic refers to cylinder rod seals, pump shaft seals and constantly flexing hydraulic hose.
Applications
- Replacement for anti-wear, mineral oil-based hydraulic fluids in applications where fire hazards exist
- Environmentally sensitive hydraulic applications
- Hydraulic systems using components from all major manufacturers
