R/RX/BX/IX/AX Lens/Oval/Octagonal API Metal Ring Joint Gasket Description:
API Ring Joint Gasket comes into two basic types,an oval cross section and an octagonal cross section.These basic shapes are use in pressures up to 10,000psi.The dimensions are standardized and require specially grooved flanges.The octagonal cross section has a higher sealing efficeiency than the oval and would be the preferred gasket.However,only the oval cross section can be used in the old type round bottom groove.The newer flat bottom groove design will accept either the oval or the octagonal cross section.
