ASME B16.20 Type RX Ring Gasket – Pressure-Activated Sealing for API Flanges

Description

ASME B16.20 Type RX Ring Gaskets are pressure-energized, metallic gaskets designed for use in high-pressure and high-temperature environments, especially in API 6A and ASME B16.5 flanges. The RX type offers improved sealing performance over standard R-type gaskets by utilizing internal pressure to enhance the seal as system pressure increases.

Manufactured from carbon steel or stainless steel, these gaskets are available in a wide range of sizes and materials compatible with various flange standards. The RX design includes a pressure-activation feature and a self-seating capability, making it ideal for subsea, offshore, refinery, and petrochemical applications.
