RX


rx2.pngRX Type Gasket
Style RX type RTJ gaskets are manufactured in accordance with both API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges. 
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.
Pressure: 2,000-5,000 PSI
