NEOPRENE All purpose. Resistant to vegetable oils. Generally not affected by moderate
chemicals, fats, greases and many oils and solvents. Generally attacked by strong oxidizing acids,
ketones, esters, nitro hydrocarbons and chlorinated aromatic hydrocarbons.
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.

FKM (Fluorocarbon)
Shows good resistance to a wide range of oils and solvents; especially all
aliphatic, aromatic and halogenated hydrocarbons, acids, animal and vegetable oils. Hot water or hot
aqueous solutions (over 70 ° F) will attack FKM.

EPDM Shows very good water and chemical resistance. Has poor resistance to oil and solvents,
but is fair in ketones and alcohols.
STAINLESS STEEL CF-8M equal to or exceeding ASTM specification A743 for corrosion resistant iron chr
omium, iron chromium nickel,
and nickel based alloy castings for general applications. Commonly referred to as 316 Stainless Steel in the pump industry.

*Definite reduction in service life.
**Minimal reduction in service life at ends of range.
For specific applications, always consult The Warren Rupp Chemical Resistance Chart.
