Style RX is a pressure-energized adaptation of the standard Style R gasket. The RX is designed to fit the same groove design as a standard Style R, making the joints interchangeable. The modified design uses a pressure-energized effect that improves the efficiency of the seal as the internal pressure of the system increases.
NOTE 1:
The pressure passage hole illustrated in the Ring Type Joint cross section ensures equalisation of pressure which may be trapped in the
grooves, it is in ring RX82 through RX91 only. Centre line of hole shall be located at mid point of dimension"c"(width flat).Hole diameter shall be as
