Compounds specifically formulated for exploration and production applications



The upstream sector of the oil and gas industry poses unique challenges for sealing companies. It’s not unusual to see environments where temperatures can reach 260°C (500°F), pressures can exceed 10,000 psi, and the applications can be extremely caustic. These examples are just a few of the many inquiries we can receive at KC Seals. Our O-Ring materials are oil field-proven and are specifically formulated for the harsh environments typically seen in exploration and production applications. This includes compounds that offer resistance to temperature, extrusion, H2S, rapid gas decompression, and superheated steam. We also offer compounds that are both NORSOK M710 and API 6A certified.
