Ring Joint Gasket

Stainless Steel Gaskets

Ring Joint Gaskets are precision-engineered components designed for high-pressure applications. They are commonly used in the oil and gas industry, particularly in offshore and onshore drilling operations, and in high-pressure valve and pipework systems. Made from solid metal rings, these gaskets are capable of withstanding extreme pressure and temperature conditions.


These gaskets conform to international standards such as API, ASME, and ANSI, ensuring compatibility and reliability across a range of industrial applications. Their robust design and material composition make them ideal for maintaining a secure seal under the most demanding conditions.

Application of Ring Joint Gaskets:

Ring joint gaskets are known for their high pressure and temperature resistance, making them ideal for demanding applications. They are primarily used in:

  • Oil and gas industry for sealing high-pressure flanges and connections.
  • Petrochemical plants to ensure leak-proof seals in process equipment.
  • Refineries for flanges in reactors and other high-temperature applications.
  • Chemical processing for high-pressure vessels and piping systems.
  • Power generation for steam and high-pressure applications in turbines and boilers.
  • Marine applications for critical flanged joints on ships and offshore platforms.
