Metal O-ring Seal – High-performance, durable sealing solution for extreme temperatures & pressures. Ideal for aerospace, automotive, and industrial applications. Made from stainless steel, copper, or other alloys for superior corrosion resistance. Ensures leak-proof, reliable performance in harsh environments. Custom sizes & materials available.
Metal O-ring Seal are typically created from tubing, which usually contains high-temperature alloys (Inconel) or stainless steel.Metal O-ring Seal 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 Standard Type Metal O-ring Seal
The Standard Type of Metal O-ring Seal, 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-ring Seal 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 Metal O-ring Seal
The Pressure-filled Type of Metal O-ring Seal 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.
