High Light: ASME B16.20 RX Ring Joint Gasket, SS410 seal ring gasket, SS410 ring type joint gasket
We Manufacture and supply high quality Ring joint Gaskets for high pressure and temperature service conditions. These gaskets are widely used in Refineries, Petrochemical Industries, Oil drilling well head equipments, Pressure Vessels, valves, Christmas Tree valves and Pipe lines. Ring joints Gasket are strictly manufactured as per API-6A and ASME B16.20 specification.
Ring type joint gasket (RTJ Gasket) is a high integrity sealing gasket, high temperature and high pressure gasket for applications in petroleum industry, oilfield drilling, pressure vessels joints, pipes and valves etc
The RX type RTJ gasket is manufactured in accordance to API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges. The RX is a pressure energized version of the R octagonal gasket and fits the R type flat bottomed groove. The RX has an increased height and utilizes the internal system pressure to energize and improve the seal as internal pressure increases. Some RX sizes have a pressure relief hole to equalize pressure on both sides of the sealing faces.
Ring joint gaskets (RTJ Gasket) according to API 6A and ASME B16.20 for numerous industrial applications based on the customer required specifications with corrosive protection using electroplated zinc or alternate material coating of up to 0.0003” thickness.

–NB1 1/2″ to 24″ Class Rating 720 to 5000 ASME B16.20
–NB26″ to 36″ Class Rating 300 to 900 ASME B16.20 Series A
–NB1 1/2″ to 20″ Class Rating API 6A
RX 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.
