Types R or  RX  gaskets shall be used on 6B flanges with type R grooves. Only BX gaskets shall be used with 6BX flanges with type BX grooves. NOTE: RX and BX gaskets provide a pressure-energized seal but are not interchangeable. RX gaskets provide additional clearance between the flanges. Ring gaskets have a limited amount of positive interference, which ensures that the gaskets are coined into a sealing relationship in the grooves and therefore RING GASKETS SHALL NOT BE REUSED. Ring gaskets shall be API Monogrammed in accordance with the requirements of API 6A latest edition and marked per Table A-16.<\/p>\n\n\n\n
