BX-162 Ring Joint Gasket – Low Carbon Steel (Zinc Plated) API 6A RTJ Sealing Ring

The BX-162 Ring Type Joint (RTJ) Gasket is a high-performance, pressure-energized metal sealing ring engineered specifically for use with large-diameter 16-3/4" API 6BX flanges in high-pressure oilfield applications. Designed to handle extreme operating pressures ranging from 5,000 PSI up to 10,000 PSI (5K/10K), the BX-162 delivers a robust, blowout-proof seal essential for heavy-duty wellheads, blowout preventers (BOPs), and critical subsea and surface manifold systems.

Manufactured from premium Low Carbon Steel (LCS), this gasket is precision-machined and then zinc-plated (or treated with a comparable corrosion inhibitor) to prevent surface oxidation and ensure maximum integrity during storage and field installation. The BX series features a highly specialized geometry that allows for complete face-to-face contact between the mating flanges upon makeup. Once fully torqued, the gasket is totally enclosed within the flange groove, making the connection exceptionally resistant to mechanical shock, intense vibration, and severe temperature fluctuations.

The pressure-energized design dictates that as internal system pressure increases, the sealing force driving the gasket against the flange's sealing surfaces actively intensifies, guaranteeing a bubble-tight metal-to-metal seal. Additionally, the BX-162 features a standard precision-drilled pressure-equalizing vent hole to prevent fluid or gas entrapment behind the ring, ensuring safe and predictable performance during system depressurization.

Features & Benefits

• Pressure-Energized Technology: Utilizes internal line pressure to dynamically increase the sealing force against the flange groove, ensuring fail-safe reliability under 5,000 to 10,000 PSI conditions.

• Low Carbon Steel Construction: Provides the ideal ductility to safely deform into the harder flange groove to create a perfect seal, while maintaining exceptional structural yield strength.

• Corrosion Protection: Finished with specialized zinc plating to resist rust and environmental degradation prior to and during installation in harsh field conditions.

• Integrated Vent Hole: Features a precision-drilled cross-hole to equalize pressure across the gasket, preventing dangerous fluid or gas entrapment in the groove.

• API 6A & ASME B16.20 Compliant: Machined to strict dimensional and hardness tolerances to ensure full interchangeability and to prevent damage to expensive mating flange faces.

• Face-to-Face Mating: Designed specifically for large-bore 16-3/4" API 6BX flanges, allowing the flange faces to meet perfectly for a more rigid, load-bearing, and protected connection.

Specifications & Technical Details

Applications

The BX-162 Low Carbon Steel Gasket is widely utilized in high-pressure drilling, completion, and production environments involving large-bore equipment. Typical applications include critical connections on 16-3/4" Blowout Preventer (BOP) stacks, heavy-duty wellhead assemblies, frac trees, and deepwater subsea control systems where the safe containment of 5K to 10K PSI fluids is non-negotiable.

Quality Assurance

Each BX-162 gasket is manufactured under rigorous quality control standards. We perform strict hardness testing to ensure the ring remains softer than the mating flange, preventing groove damage while ensuring the metal-to-metal seal is fully formed. Every gasket is visually and dimensionally inspected, with full material traceability provided to guarantee maximum safety and reliability in the field.
