ISO Centering Ring with Outer Ring and Oring
The ISO Centering Ring with Outer Ring and O-Ring is a vacuum fitting component that is used to provide a leak-tight and centered connection between a vacuum flange and a tube. The centering ring is designed to fit into the recess of the flange and provides a smooth and even surface for the O-ring to seal against. The outer ring provides additional support and stability to the connection. The O-ring seals against any leaks, ensuring that the system remains at the desired vacuum pressure. This type of centering ring is commonly used in high-vacuum systems where a secure and leak-free connection is critical. The ISO standard ensures compatibility between components from different manufacturers.
