LONESTAR Ring Gasket BX-163, BX-164
Product Overview
In high-pressure oil & gas operations, sealing integrity is not optional, it is mission critical. A single flange failure can result in operational shutdown, environmental hazard, or severe safety risk. That is why precision-engineered Ring Type Joint (RTJ) gaskets are used in demanding upstream applications.
KKD Marine & Industrial Supplies offers LONESTAR Ring Gaskets BX-163 and BX-164, designed specifically for API 6A BX groove flanges used in wellhead systems, offshore drilling rigs, and high-pressure production lines.
These metallic ring gaskets are engineered to create a metal-to-metal interference seal, ensuring reliable containment under extreme pressure and temperature conditions. When installed correctly, the BX gasket deforms into the precision-machined flange groove, forming a tight seal capable of withstanding severe operational environments.
As a trusted supplier of rig consumables and oilfield sealing solutions, KKD Marine ensures that every gasket supplied meets industry requirements and performance expectations.
What Makes BX Type Gaskets Critical?
Unlike conventional soft gaskets, BX ring gaskets are:
• Solid metal construction
• Designed for extreme pressure classes
• Compatible only with API 6A BX flanges
• Pressure-energized for enhanced sealing
• Engineered for oilfield wellhead applications
The BX profile includes a pressure balance hole, which prevents pressure trapping and enhances sealing stability in high-pressure operations.
Applications
The LONESTAR BX-163 and BX-164 are widely used in:
Wellhead Assemblies

How the Sealing Mechanism Works
The BX gasket functions through controlled deformation:
- The gasket is seated inside the precisely machined BX groove.
- As flange bolts are torqued, the ring compresses.
- The metallic surfaces plastically deform into each other.
- Internal system pressure enhances the sealing force.
- The balance hole prevents pressure entrapment within the groove.
This design ensures exceptional resistance to:
• High internal pressure
• Thermal cycling
• Vibration
• Mechanical stress

Industry Importance
In upstream oil & gas operations, RTJ flange joints operate under some of the most extreme mechanical conditions in the industrial world. BX-type ring gaskets are selected where:
• Pressure levels are exceptionally high
• Safety compliance is mandatory
• Maintenance access is limited
• Reliability is critical
Failure in such environments is not acceptable, which is why precision-engineered ring gaskets are used instead of conventional gasket solutions.
Frequently Asked Questions (FAQ)
1. What is the difference between BX and RX gaskets?
BX gaskets are designed for higher pressure API 6A flanges and are not interchangeable with RX types.
2. Can BX-163 be used in standard ASME flanges?
No. BX gaskets are only compatible with API 6A BX groove flanges.
3. Are these gaskets reusable?
RTJ gaskets are generally recommended for single use due to metal deformation during installation.
4. What industries use BX ring gaskets?
Primarily oil & gas drilling, offshore production, and high-pressure wellhead systems.
5. What material should be selected?
Material depends on pressure, temperature, and corrosive environment requirements.
6. Do these comply with API standards?
Yes, BX gaskets are manufactured as per API 6A requirements.
7. What is the function of the balance hole?
It prevents trapped pressure between the flange groove and gasket.
8. Do you provide material test certificates?
Yes, certification can be provided upon request.
9. Can you supply urgently for offshore rigs?
Yes, KKD Marine supports urgent supply requirements.
10. What pressure range are BX gaskets designed for?
They are designed for high-pressure oilfield applications, often used in extreme service conditions.
