Ring Joint Gasket

Ring Joint Gasket is manufactured by CNC equipment according to ASME B16.20 and API 6A standard.

 

 

 

 

  • R(Oval)Ring joint gasket with oval cross section, suitable for ANSI B 16.5,ASME B16.47, series A flange, can be used in pressures up to 1000 PSI
  • R(Octagonal)Ring joint gasket with octagonal cross section are designed for flanges with standard grooves,interchangeable with oval ring joint gaskets on modern octagonal grooved flanges, but has a higher sealing ability.
  • RX Ring joint gasket is designed for pressures up to 5,000 PSI. They are interchangeable with R-oval or R-octagonal rings used on API 6B flanges.
  • BX Ring joint gasket can only be used with 6BX flanges and 16BX hubs. BX Gaskets are designed for higher-pressure ratings starting at 5,000 lbs. and ending with 20,000 lbs.
