RX type gasket
The RX type RTJ ring gasket is manufactured in accordance with API 6A and ASME B16.20 standards, and is suitable for API 6B and ASME/ANSI B16.5 flanges.
RX type is a standard R-type gasket that adapts to pressure energy. The RX type is designed to accommodate the same standard R-slot design, allowing for interchangeable joints. The modified design utilizes pressure energy to increase the internal pressure of the system and enhance the efficiency of sealing.
Pressure: 2000-5000 PSI
Tolerance: (mm)
A * (width of the ring)
+ 0.20，-0.000
H (height of the ring)
+ 0.20，-0.000
Outer diameter (outer diameter)
+ 0.5，-0.000
23 * (angle)
1/2°
*The width tolerance is 0.008 inches.
A "and height" H "are allowed as long as the variation in width or height does not exceed 0.004 inches along the entire circumference.
Note 1:
The pressure channel hole indicates that ensuring balanced pressure at the cross-section of the ring joint may be trapped in the groove, and it is located in ring RX82 through RX91. The centerline of the hole should be located at the midpoint of "C" (wide flat). The diameter of the hole should be A.
