Oval and Octagonal Ring Type Joints (RTJs) supplied by AMG Sealing are precision-manufactured metallic sealing rings designed for high-pressure flange connections with standard ring type grooves. Commonly used throughout the oil & gas, petrochemical, offshore, and energy industries, these ring joints provide dependable, high-integrity sealing performance in demanding operating conditions.
Manufactured to high-quality standards and suitable for pressures up to 5,000 psi in accordance with API 6A, Oval and Octagonal cross-section RTJs are widely trusted for critical pressure sealing applications.
Oval & Octagonal Ring Joint Types
- Octagonal Ring Type Joints feature a more efficient sealing profile and are generally preferred for higher sealing performance in standard API ring groove flanges.
- Oval Ring Type Joints were originally designed for older type round-bottom grooves but remain fully interchangeable with Octagonal RTJs in flat-bottom groove designs.
- Suitable for high-pressure, high-temperature flange-sealing applications.
- Available in a wide range of standard sizes and materials to suit customer requirements.
