BX Ring Joint Gasket – precision-engineered metal sealing rings manufactured in China by Kaxite. Designed for API 6A and ASME B16.20 flanges, these high-integrity gaskets deliver leak-proof performance in extreme pressure and temperature environments.
BX Ring Joint Gasket is a high-strength, pressure-energized metal sealing ring manufactured from solid bar stock through precision CNC machining. Designed for API 6BX flanges used in high-pressure oil and gas wellhead equipment, Christmas trees, and manifold systems, the BX design features a higher pressure rating and improved sealing geometry compared to standard R or RX styles. As a trusted China ring joint gasket supplier, Kaxite produces these critical seals from a wide range of materials including stainless steel, Inconel, Monel, Hastelloy, and duplex alloys.
The BX gasket incorporates a pressure-energized sealing principle – as flange bolt load is applied, the gasket metal flows into the flange groove, creating a positive metal-to-metal seal. Internal pressure further energizes the seal, making BX gaskets ideal for wholesale ring joint gasket procurement in upstream oil and gas operations, subsea production systems, and high-pressure gas storage facilities.
