Material Compatibility
Elastomers
The chart contains our recommendations regarding the use of Hysyn FR Series with commonly used elastomers.
Three categories of elastomer applications are listed. “Static” refers to trapped nonmoving seals such as 0-rings in
valve subplates and rigid, low pressure hose connections. “Mild-Dynamic” applications include accumulator bladders and hose linings where the hoses are exposed to high pressure and light flexing. “Dynamic” refers to cylinder
rod seals, pump shaft seals and constantly flexing hydraulic hose.

Elastomer Compatibility

C = Compatible
S = Okay for short-term use, but replace with a completely compatible elastomer is recommended at the earliest convenience
N = Not compatible
Metals
HYSYN FR Series is compatible with iron and steel alloys and most nonferrous metals and their alloys. HYSYN FR Series is
not compatible with lead, cadmium, zinc, and alloys containing high levels of these metals. Suitable substitutes for these materials are available and should be used.
Paints and coatings
HYSYN FR Series is compatible with multicomponent epoxy coatings. HYSYN FR Series is not compatible with zinc-based
coatings. Specific coating and application recommendations can be obtained from coating manufacturers or directly from
Summit Industrial Products

Conversion Procedures
Mineral oil-based fluids
HYSYN FR Series fluids are miscible and compatible with nearly all mineral oil-type hydraulic fluids. To convert a system
using these types of fluids, simply drain and recharge with HYSYN FR Series. For proper fire resistance, at least 95% of the
oil-based fluid should be removed.
Water glycol (HFC) and invert emulsions (HFB)
HYSYN FR Series fluids are not miscible or compatible with water-containing fluids and these fluids must be removed
from the system. Remove most of the fluid by draining the reservoir and lines. Remove residual fluid by circulating HYSYN
FR Series and draining. Refill with fresh fluid. Repeat until residual fluid is less than 1% of system volume.
Phosphate ester
HYSYN FR Series fluids are compatible with some, but not all phosphate esters. Testing prior to conversion is recommended.
Please contact Summit Industrial Products for testing and conversion recommendations.
