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.
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.
Urethane Shows good resistance to abrasives. Has poor resistance to most solvents and oils.
Santoprene ® Injection molded thermoplastic elastomer with no fabric layer. Long mechanical flex life. Excel-
lent abrasion resistance.
Maximum Minimum
‡ CF-8M Stainless Steel equal to or exceeding ASTM specification A743 for corrosion resistant iron chro-
mium, iron chromium nickel, and nickel based alloy castings for general applications. Commonly referred
to as 316 Stainless Steel in the pump industry.

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.
