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.

–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.
