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.

Advantages

High-temperature capability

Ability to withstand low temperatures

Present vacuum

Ability to withstand extreme applications (radioactive, corrosive)

Reusable in many cases

Present a long-term seal – no material disintegration

Long storage life

Self-energizing forcesOptimized spring  back, load and outer sealing layered hardness

Chemical compatibility

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.
