Ring joint gaskets are designed for high pressure applications. They are available in a variety of forms to suit different flange formats. It can be used for very high and/or fluctuating pressures (up to 1500 bar), depending on the profile selected. Material selection determines use for high temperatures (up to 1000 °C) and in aggressive media. To ensure proper sealing the surface of contact between the gaskets and flange have to be carefully processed. The small sealing area and high contact pressure results in excellent sealability.
