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. This product has a shelf life of 12 months, and it should be stored in a tightly sealed container in temperatures between 0 – 40°C.
Applications
QUINTOLUBRIC® 855 was designed to replace anti-wear, mineral oil-based hydraulic fluids as well as vegetable based fluids and polyol esters. QUINTOLUBRIC® 855 can be used in or near fire hazards and in environmentally sensitive hydraulic applications without compromising the overall hydraulic system operation.
Recommendation for Use
QUINTOLUBRIC® 855 is recommended for use in systems with a maximum operating temperature of 70°C (150ºF), in combination with partial refreshment by system leakage.
QUINTOLUBRIC® 855 is used as received and pre-filtration is not necessary because the fluid is filtered during production. Its higher viscosity index compared with mineral oil makes it ideal for use at a wider temperature range. QUINTOLUBRIC® 855 also has good cold start-up properties and offers a higher viscosity at increased temperatures.

| Thermal Conductivity at 19ºC (D2717) | 0.167 | J/sec/ m/ºC |
Fluid Maintenance
In order to lengthen fluid life, the product should be kept free from water and dirt. High temperatures should also be avoided. We recommend a program of regular fluid analysis (no less than twice per year).
Compatibility
Metal
QUINTOLUBRIC® 855 is compatible with iron and steel alloys and most non-ferrous metals and their alloys. It is not compatible with lead, cadmium and has limited compatibility with alloys containing high levels of these metals. QUINTOLUBRIC® 855 has limited compatibility with hot dipped or electro galvanised surfaces and good compatibility with zinc containing alloys. Suitable substitutes for these materials are available and should be used.
Paints and Coatings
QUINTOLUBRIC® 855 is compatible with multicomponent epoxy coatings. It shows limited compatibility with one component (zinc-dust containing) coatings. Specific coating and application recommendations can be acquired from coating manufacturers or directly from Quaker Houghton.
Fluids
QUINTOLUBRIC® 855 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.
