O-ring sealing systems are ubiquitous in oil/gas field applications and have been extensively tested. The general relationships between O-ring designs and their performances are well known; however, O-ring extrusion failure is still frequently encountered in various applications. As a result, there still is a need to test standard O-rings when changes in materials, sealing gland configuration or service temperatures occur.
This study is intended to uncover universal relationships between O-ring design parameters and their extrusion-resistance performance.
