This EPDM O-ring has a shore durometer of 70 A, and is designed for use in a wide variety of sealing applications.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 indentation.
EPDM has excellent ozone,weather,deformation,acid,alkalion,water swell,steam,tensile strength,and chemical resistance.EPDM is acceptable for temperature applications between -50 degrees C to 150 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 meets standards defined by Aerospace Standard AS568, which is the Aerospace Size Standard for O-rings.
