When it comes to high-pressure sealing in the oil and gas, geothermal, petrochemical, and industrial sectors, few products are as critical as the Ring Joint Gasket (RTJ Gasket).
Designed to operate under extreme pressure and temperature conditions, Ring Joint Gaskets provide a metal-to-metal seal that delivers exceptional reliability where conventional soft gaskets would fail.
At Safety Shark, we supply high-quality Ring Joint Gaskets manufactured in China to API specifications and suitable for demanding drilling and production applications worldwide.
What is a Ring Joint Gasket?
A Ring Joint Gasket (RTJ Gasket) is a precision-machined metallic sealing ring designed to fit into specially machined grooves on RTJ flanges.
When flange bolts are tightened, the gasket deforms slightly, creating a highly effective metal-to-metal seal capable of withstanding extreme operating conditions.
Common Applications
- Oil & Gas Production
- Geothermal Drilling
- Wellhead Equipment
- BOP Systems
- High Pressure Flowlines
- Refineries
- Petrochemical Plants
- Pressure Vessels
Types of Ring Joint Gaskets
R Type Ring Joint Gaskets (Click here to see in store)
The R-Type gasket is the most commonly used RTJ gasket and is available in:
- Oval Section
- Octagonal Section
R-Type gaskets are commonly used with API 6A flanges and are suitable for a wide range of pressure classes.
Best For:
- Wellheads
- Christmas Trees
- Production Equipment
- General RTJ Flanges
RX Type Ring Joint Gaskets (Click here to see in store)
RX gaskets are pressure-energized designs intended for higher pressure applications.
As internal pressure increases, the sealing efficiency also increases, making RX gaskets ideal for critical service conditions.
Key Features
- Self-energizing design
- Interchangeable with corresponding R-Type grooves
- Suitable for pressures up to approximately 700 bar
- Improved sealing performance over standard R rings
BX Type Ring Joint Gaskets (Click here to see in store)
BX gaskets are designed for extremely high-pressure service.
Unlike R and RX styles, BX rings are only compatible with BX flange grooves.
BX rings feature a pressure equalization hole that helps improve sealing performance under extreme pressure conditions.
Key Features
- Designed for very high-pressure service
- Suitable for pressures up to approximately 1,500 bar
- Pressure equalization hole
- Compatible only with BX flanges

Common Ring Joint Gasket Materials
Selecting the correct material is critical for sealing performance and flange protection.
| Material | Identification | Maximum Hardness |
| Soft Iron | D | 56 HRBW |
| Low Carbon Steel | S | 68 HRBW |
| Stainless Steel 304 | S304 | 83 HRBW |
| Stainless Steel 316 | S316 | 83 HRBW |
Other materials may be available upon request depending on service conditions.
How to Identify the Correct Ring Gasket
When requesting a quotation, provide:
- Ring Number (Example: R57, RX73, BX159)
- Material Grade
- Quantity Required
- Flange Size
- Pressure Rating
- Applicable Standard (API, ASME, etc.)
Example:
R-57 – Soft Iron
RX-73 – SS316
BX-159 – SS304
