Ring Joint Gaskets

• Available in oval and octagonal cross-sections
• Style R gaskets are interchangeable on modern octagonal flat bottom grooved flanges
• Standard sizes of Style R gaskets are manufactured in accordance with ASME B16.20 and API 6A specifications

• The Style RX ring joint has a unique self-sealing action. The outside bevels of the ring make the initial contact providing a seal against the grooves outer surfaces. As the internal pressure increases, so does the gasket loading stress against the groove thus improving the gaskets sealing characteristics
• Design features of the Style RX gasket make it more resistant to shock load, test pressure shock and drilling vibration
• Style RX ring joints are completely interchangeable with standard Style R groove designs. Care should be taken when interchanging these styles as RX gaskets are taller and will add length to the finished assembly

• Style BX gaskets have a pitch diameter slightly larger than the groove pitch diameter. This allows for initial contact to be made on the outside of the ring, pre-loading the gasket which creates a pressure energized seal
• All Style BX gaskets incorporate a pressure passage to enable trapped pressure to balance itself in the joint
• Style BX ring joint gaskets can only be used with API BX flanges and are not interchangeable with style RX
