A Ring Type Joint Flange, commonly referred to as an RTJ Flange, is a flange designed to provide a leak-proof sealing solution in high-pressure applications. Unlike standard flanges, RTJ Flanges utilize a metal ring gasket seated in a precisely machined groove on the flange face. This configuration creates a superior seal capable of withstanding extreme pressures and temperatures.
