RX Type Ring Joint Gasket

Product Description

RX TYPE ring joint gasket are designed for pressures up to 5,000 PSI. These gaskets are interchangeable with R-oval or R-octagonal rings used on API 6B flanges. RX type gaskets provide excellent performance in 6B flanged blowout preventer stacks, which require the additional mass of the RX gasket to support the higher pressures, higher vibrations and heavier weights of this type of equipment. Gaskets that have been torqued initiating a metal-to-metal seal should be discarded and not reused.
