The Junio Style RX ring-joint gasket is an adaptation of the standard Style R which energizes on assembly. The RX ring joint gasket is designed to fit the same groove design as a standard Style R, making the joints interchangeable.

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.
