Oval/Octagonal Ring Joint Gasket

Ring Joint Gaskets are designed to seal by "initial line contact" or wedging action between the mating flange and the gasket. Usually used in oil, petroleum and chemical process fields. Precision machined, metallic sealing rings suitable for high pressure and high temperature applications.
Ring Joint Gasket Types:
Type R  ( oval/ octagonal ) 
R Style is available in both oval and octagonal configurations, the octagonal type is recommended in higher sealing efficiency, both types are interchangeable on modern octagonal type grooved flanges. However,only the oval cross section can be used in the old type round bottom groove.  
Type RX 
RX is a pressure- energized adaptation of the standard Style R gasket. The modified design uses a pressure - energized effect that improves the efficiency of the seal as the internal pressure of the system increases.   
Type BX 
BX pressure energized gaskets are manufactured in accordance with API 6A and are designed for use on pressurized systems up to 20,000 PSI. on both the inner and outer diameters. All BX gaskets incorporate a pressure balance hole to ensure equalization of pressure that may be trapped in the grooves.
