|---|---|---|---|
| R Type | Basic type available in oval and octagonal shapes. | Up to 6,250 psi | General applications in flanged joints. |
| RX Type | Similar to octagonal but designed for pressure-energized sealing. | Up to 15,000 psi | Oil field drilling and production. |
| BX Type | Square cross-section, designed for API 6BX flanges. | Up to 20,000 psi | High-pressure applications. |
| SRX Type | Vented design to prevent pressure lock in subsea applications. | Up to 15,000 psi | Subsea wellhead and tree equipment. |
| SBX Type | Similar to SRX but designed for higher pressure ratings. | Up to 20,000 psi | Subsea applications. |
R Type Gaskets
R type gaskets are the most common and are available in both oval and octagonal configurations. They are designed for sealing pressures up to 6,250 psi and are suitable for various flanged connections. The octagonal type is preferred for higher sealing efficiency.
RX Type Gaskets
RX type gaskets are designed to take advantage of contained fluid pressure, enhancing the sealing capability. They are interchangeable with standard octagonal rings and are used in applications requiring pressures up to 15,000 psi.
BX Type Gaskets
BX type gaskets are engineered for the highest pressure ratings, specifically for API 6BX flanges. They are square in cross-section and can handle pressures up to 20,000 psi, making them ideal for critical applications in the oil and gas industry.
SRX and SBX Type Gaskets
Both SRX and SBX gaskets are designed for subsea applications. They feature vent holes to prevent pressure lock when connections are made underwater. These gaskets have identical measurements to RX and BX types, ensuring compatibility with existing systems.
