Sur-Seal OR90CLRURE237 237 90 D O-Ring Urethane
With a durometer of A90 (hard), these Sterling Seal, Inc Urethane O-Rings are
harder and are better for high-pressure applications than high-strength
polyurethane Temperature range is -65 to 275 F Cast polyurethane is
outstanding over other O-Ring elastomers in abrasion resistance and tensile
strength Additionally, cast polyurethane surpasses the performance of millable
polyurethane in its higher tensile strength, greater elongation, wider
temperature range, and lower compression set characteristics These seals are
ideal for high hydraulic pressures and situations where highly stressed parts
are subject to wear They are used for wheels, rolls, slurry parts, bumpers,
couplers, and shock absorbers Also used for wiper seals for axially moving
piston rods Temperature range for the standard compound is -30 to +175f With
tensile strength of up to 6, 000 psi, elongation of 350 to 650 percent,
compression sets of 10 to 25 percent, and exceedingly high abrasion
resistance, the physical properties of cast polyurethane are among the best of
all O-Ring elastomers Although they swell slightly upon exposure, cast
polyurethane compounds feature excellent resistance to mineral-based oils and
petroleum products, aliphatic solvents, alcohols and ether They are also
Compatible with hydraulic fluids, weak acids and bases, and Mixtures
containing less than 80 percent aromatic constituents Cast polyurethanes are
not recommended for exposure to concentrated acids and bases, ketones, esters,
very strong oxidizing agents, Pure aromatic compounds and brake fluids With
the exception of special compounds, they are also not recommended for exposure
to hot water or steam Common end use applications are industrial seals,
industrial rolls, O-Rings, caster wheels, gaskets, Shoe soles and conveyor
belts
