Metal O Rings are typically created from tubing, which usually contains high-temperature alloys (Inconel) or stainless steel.Metal O Rings are a high-performance sealing solution and are designed to enhance the performance of extreme applications.These seals are ideas as static face type seal; however, they are not recommended to be used as a dynamic seal. Therefore, they work just like a gasket between two flanges, which have a very little or no movement between them. They are produced not only in circular shape but also rectangular and many more diverse shapes and configurations.

Self-energizing forcesOptimized spring back, load and outer sealing layered hardness
Chemical compatibility
Types
the Standard Type
The Standard Type of metal O-rings, made from various metallic tubings or solid wire, is an economical choice for applications with low to moderate pressure or vacuum ratios
the Self-energizing Type
The Self-energizing Type of metal O-rings feature borings and grooves on the inside or outside diameter, allowing the O-ring to experience the same pressure as the system. This design leverages the system pressure to enhance the sealing performance
the Pressure-filled Type
The Pressure-filled Type of metal O-rings is specifically designed for high-temperature applications ranging from 425 degrees Celsius to 980 degrees Celsius. These O-rings contain a gas filling of approximately 40 bar pressure or higher. The gas pressure increases with rising temperatures, compensating for the initial tension deficiency of the flanged joint and increasing the sealing force. While they offer lower pressure resistance compared to the self-energizing type, they excel in high-temperature environments.
Non-circular geometric and custom shapes.
It can be customized according to user needs, made into square, diamond, waist shape, or spring reinforced typeRacetracks etc.
