What is Ring Gasket?

A Ring Gasket, also known as a Ring Type Joint (RTJ) Gasket, is a precision-machined metallic sealing ring designed for high-pressure and high-temperature applications. It is commonly used in the oil and gas, petrochemical, offshore, and drilling industries where reliable sealing performance is critical.

RTJ gaskets are installed in specially machined grooves on flanges and create a metal-to-metal seal when compressed. Due to their exceptional sealing capability, Ring Gaskets are widely used in wellhead equipment, Christmas trees, choke and kill manifolds, pressure vessels, and pipeline systems operating under extreme conditions.

Ring Gaskets are manufactured in accordance with API 6A and ASME standards and are available in various profiles including R Oval, R Octagonal, RX, and BX types. They can be produced from a wide range of materials such as Soft Iron, Carbon Steel, Stainless Steel 304/316, Duplex Stainless Steel, and Inconel to suit different operating environments.

At OilandGasMart, we supply high-quality Ring Gaskets for demanding industrial applications, ensuring reliable sealing performance, dimensional accuracy, and compliance with international standards.

BX Ring Gasket

BX Type Ring Gaskets are specially designed for high-pressure API 6BX flanges used in critical oil and gas applications. The BX profile features a pressure-energized design that enhances sealing performance as internal pressure increases, making it one of the most reliable metallic sealing solutions for extreme operating conditions.

BX Ring Gaskets provide metal-to-metal sealing and are manufactured to precise dimensional tolerances in accordance with API 6A specifications. They are commonly used in wellhead systems, Christmas trees, choke and kill manifolds, drilling equipment, and other high-pressure applications where leakage prevention is critical.

Available in a variety of materials including Soft Iron, Carbon Steel, Stainless Steel, Duplex Stainless Steel, and Inconel, BX Ring Gaskets offer excellent resistance to pressure, temperature, and corrosive environments.

Key Features

- Designed for API 6A flanges

- Pressure-energized metal-to-metal seal

- Suitable for extremely high-pressure service

- Excellent sealing performance and reliability

- Manufactured in accordance with API 6A standards

RX Type Ring Gaskets are pressure-energized metallic sealing rings specifically designed for use with API 6B flanges in high-pressure oil and gas applications. The RX profile is an improved version of the standard R-type gasket, providing enhanced sealing efficiency and greater reliability under elevated pressure conditions.

The unique geometry of the RX Ring Gasket allows internal system pressure to assist in energizing the seal, resulting in improved leak prevention and sealing performance compared to conventional R Oval and R Octagonal ring gaskets. This makes RX gaskets ideal for critical applications where safety and operational integrity are essential.

Manufactured in accordance with API 6A specifications, RX Ring Gaskets are precision-machined to ensure dimensional accuracy and consistent sealing performance. They are available in various material grades, including Soft Iron, Carbon Steel, Stainless Steel, Duplex Stainless Steel, and Inconel, to meet different pressure, temperature, and corrosion requirements.

R-Oval Ring Gasket

R Oval Ring Gaskets are metallic sealing rings designed for Ring Type Joint (RTJ) flange connections in high-pressure and high-temperature applications. As one of the most widely used RTJ gasket profiles, the R Oval design provides reliable metal-to-metal sealing performance for critical oil and gas operations.

Manufactured in accordance with API 6A and ASME B16.20 standards, R Oval Ring Gaskets are engineered to fit standard RTJ flange grooves and create a secure seal when compressed between mating flange faces. Their oval-shaped cross-section allows effective sealing under demanding operating conditions, making them suitable for both new installations and replacement applications.

R Oval Ring Gaskets are commonly used in wellhead equipment, drilling systems, pressure vessels, pipelines, valves, and offshore oil and gas facilities. They are available in a variety of materials, including Soft Iron, Carbon Steel, Stainless Steel 304/316, Duplex Stainless Steel, and Inconel, to meet specific pressure, temperature, and corrosion resistance requirements.

Key Features

- Designed for RTJ flange applications

- Manufactured to API 6A and ASME B16.20 standards

- Reliable metal-to-metal sealing performance

- Suitable for high-pressure and high-temperature service

- Available in multiple material grades

- Precision-machined for dimensional accuracy

R Octagonal Ring Gaskets are precision-machined metallic sealing rings designed for Ring Type Joint (RTJ) flange connections in high-pressure and high-temperature applications. Featuring an octagonal cross-section, this gasket design provides a more concentrated sealing load compared to the R Oval profile, resulting in enhanced sealing performance for critical industrial services.

Manufactured in accordance with API 6A and ASME B16.20 standards, R Octagonal Ring Gaskets create a reliable metal-to-metal seal when installed in compatible RTJ flange grooves. Due to their superior sealing characteristics, they are widely used throughout the oil and gas, petrochemical, offshore, drilling, and energy industries where leak prevention and operational safety are essential.

R Octagonal Ring Gaskets are suitable for a wide range of pressure classes and can be manufactured from various materials, including Soft Iron, Carbon Steel, Stainless Steel 304/316, Duplex Stainless Steel, Super Duplex Stainless Steel, and Inconel. Material selection can be tailored to meet specific pressure, temperature, and corrosion resistance requirements.
