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.
