For specific applications, always consult “Chemical Resistance Chart" Technical Bulletin
Nitrile
General purpose, oil-resistant. Shows good solvent, oil, water and hydraulic fluid resistance. Should
not be used with highly polar solvents like acetone and MEK, ozone, chlorinated hydrocarbons and nitro
hydrocarbons.
Maximum
Minimum
190°F -10°F
88°C -23°C
Maximum and Minimum Temperatures are the limits for which
these materials can be operated. Temperatures coupled with
pressure affect the longevity of diaphragm pump components.
Maximum life should not be expected at the extreme limits of
the temperature ranges.
