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 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
Non-circular geometric and custom shapes. (Racetracks, rectangles, ellipses, etc.)
