BX type ring joint gaskets
The BX type energized ring joint gaskets, manufactured in accordance with API 6A, are designed for use on pressurized systems up to 20,000 psi. Designs are also available for Subsea applications. All BX RTJ gaskets incorporate a pressure balance hole to ensure equalization of pressure which may be trapped in the grooves.
