Materials

Operating Temperatures

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.
