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