Health, Safety and Handling

Please consult the Safety Data Sheet (SDS) for information on storage, safe handling and disposal. The conditions or methods of handling, storage, use and disposal of the product are beyond our reasonable control – we assume no liability for any ineffectiveness of the product or any injury or damage, arising out of or in connection with these conditions.


QUINTOLUBRIC® 888-46 was designed to replace anti-wear, mineral oil-based hydraulic fluids used in applications where fire hazards exist. QUINTOLUBRIC® 888-46 can also be used in environmentally sensitive hydraulic applications without compromising the overall hydraulic system operations.



QUINTOLUBRIC® 888-46 is compatible with iron and steel alloys and most nonferrous metals and their alloys. It is not compatible with lead, cadmium and has limited compatibility with alloys containing high levels of these metals. This product has limited compatibility with hot dipped or electro galvanised surfaces and well compatibility with zinc containing alloys. Suitable substitutes for these materials are available and should be used.

Paints and Coatings

QUINTOLUBRIC® 888-46 is compatible with multicomponent epoxy coatings. It shows limited compatibility with one component (zinc-dust containing) coatings. Specific coating and application recommendations can be obtained from coating manufacturers or directly from Quaker Houghton.


QUINTOLUBRIC® 888-46 is compatible and miscible with nearly all mineral oil, phosphate esters and polyolester-type hydraulic fluids. It is not miscible or compatible with water-containing fluids. For conversion recommendations, please contact Quaker Houghton.


The following chart contains our recommendations regarding the use of this product with commonly used elastomers. The elastomer applications listed are “Static,” which refers to trapped nonmoving seals such as O-rings in valve sub-plates and rigid, low pressure hose connections; “Mild-Dynamic,” whose applications include accumulator bladders and hose linings where the hoses are exposed to high pressure and light flexing; and “Dynamic,” which refers to cylinder rod seals, pump shaft seals and constantly flexing hydraulic hose.
