Product Description

RX ring gasket

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.
RX ring gasket is a pressure-energized adaptation of the standard type R ring gasket. The RX ring gasket 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

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
