API 6A RX type ring joint gaskets is an adaptation of the standard Type R. Type RX rtj gaskets shall be used on 6B flanges with type R grooves. Consideration should be given to the difference in finished make-up distance. The modified design uses an energizing on assembly effect which improves the efficiency of the seal. Designs are also available for Subsea applications.
