EPDM is acceptable for temperature applications between -70 degrees
F (-57 degrees C) to 300 degrees F (149 degrees C). It is
compatible for use with water and steam, silicone oil and grease,
polar solvents (alcohols), acids, glycol-based brake fluids, ozone,
and weathering. It is vulnerable to many oils, gasoline, and
solvents. This material meets ASTM International standards.
This EPDM O-ring has a shore durometer of 70A. Shore durometer is
the hardness of a material, and its resistance to permanent
indentation. A higher durometer value indicates greater resistance
to indentation on a scale of 0 to 100, with 100 indicating no
O-rings commonly provide a pressure and fluid seal between
cylindrically shaped, overlapping mating surfaces and are commonly
seen in engines, faucets, flanges, valves, and various cylinders.
They are circular in shape, with a round cross section and a hole
in the center, similar to a doughnut. O-rings are available in
various sizes, and can be ordered based on required nominal inside
diameter (ID), outer diameter (OD), and cross-sectional (CS)
This EPDM O-ring meets standards defined by Aerospace Standard
AS568A, which is the Aerospace Size Standard for O-rings.
