Style BX 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.
 
The BX is designed to fit the same groove design as a standard Style R, making the joints interchangeable. The modified design uses a pressureenergized effect that improves the efficiency of the seal as the internal pressure of the system increases.
 
Pressure: 5,000-20,000 PSI
