As load bearing area of ring joint gaskets (RTJ Gasket) are small high surface stresses are produced between the sealing face and the groove, making it poor in recovery characteristics and unfit for reuse.

Surface finish of the Style R Ring Type Joint sealing faces (radiused ends of an Oval and the 23° angled faces of an Octagonal shape) shall not be greater than 1.6 μm Ra /63 μin RMS. Flexitallic Style R Ring Type Joints can bemanufactured in accordance with all relevant standardsto suit the following flange designations:
