Oil-Resistant Extreme-Pressure Stainless Steel O-Rings
Made of silver-plated 321 stainless steel, these O-rings can handle extreme pressure up to 11,000 psi. They resist grease, hydraulic oils, mineral oil, motor oil, and synthetic lubricants. These O-rings have a round profile and are suitable for a wide range of static and dynamic sealing applications. All are sized to the actual measured dimensions of SAE standard AS9373; they do not have a dash number.
