Metal O Rings are typically created from tubing, which usually contains high-temperature alloys (Inconel) or stainless steel. They are frequently used due to resilient features of these materials which make it possible for the seal to ‘spring back’

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.(Racetracks, rectangles, ellipses, etc.)

Notes

The water pattern on the surface of the flange groove needs to be consistent with the circumferential direction of the sealing ring (turning surface)
