RX Ring Designations for API 6B Flanges

RX gaskets are designed for pressures up to 10,000 PSI. These gaskets are interchangeable with R-oval or R-octagonal rings used on API 6B flanges. RX types of gaskets are more costly than your standard oval or octagonal rings, therefore not as popular. RX type gaskets perform excellent in 6B flanged blowout preventer stacks, which requires the additional mass of the RX gasket to support the higher pressures with higher vibrations and heavier weights of these units. Gaskets that have been torqued initiating a metal-to-metal seal should be discarded and not reused. Standard sizes are stocked in low carbon steel, 304 and 316.
