Octagonal Ring Type Joint (RTJ) gaskets are precision-engineered metallic sealing rings designed for high-pressure and high-temperature applications. Manufactured to API 6A and ASME B16.20 standards, these gaskets provide a reliable, leak-proof seal by being compressed into a precisely machined groove on RTJ flanges.
The octagonal cross-section offers greater sealing efficiency compared to oval RTJs, ensuring uniform contact and tighter sealing with less bolt load. They are widely used in oil & gas, petrochemical, refinery, and power generation industries, where safety and durability are critical.
