Ring-type joint (RTJ) gaskets are manufactured from metallic materials in compliance with American standard ASME B 16.20 and the API specification. Detailed monitoring of every manufacturing step guarantees that the sealing rings offer the necessary surface hardness. This creates a functional seal without damage to the flanges. This gasket type is used successfully in downstream refinery applications, for example. RTJ gaskets are also commonly used in high-pressure valves and the associated pipe connections and in pressure vessel joints.
Style R ring type joints are manufactured on oval (2962/R) and octagonal profiles (2961/R).
Both styles are interchangeable in the modern flat bottomed groove.
Octagonal profile joints are interchangeable on flat bottomes groove flanges which have a 23 degree angle groove wall
