API 6A Ring Joint Gasket, Carbon Steel, 120HB, RX Series, RX31 for 3 Inch 3000# Flanges High Pressure Sealing Service, With Zinc Coating

The API 6A Ring Joint Gasket RX31 is a high-pressure sealing component specifically designed for use with 3-inch, 3000# flanges in demanding oil and gas or petrochemical applications. Manufactured from carbon steel with a maximum hardness of 120 HB, this RX series gasket provides reliable metal-to-metal sealing performance under extreme pressure conditions. The gasket features the RX31 profile, engineered to enhance sealing efficiency by utilizing system pressure to improve the seal as pressure increases. A zinc coating is applied to the surface for added corrosion resistance and longevity, making it suitable for harsh environments. Compliant with API 6A standards, this ring joint gasket is an ideal choice for critical high-pressure applications requiring robust and leak-proof sealing.
