What shape are ring gaskets at cross-section?

Ring gaskets are designed to create a seal between two surfaces and their cross-section is typically oval in shape. This specific shape allows for uniform compression when the gasket is installed, helping to ensure a tight seal under various pressure conditions. The oval cross-section also provides a larger contact area with the flanges, which enhances the gasket's ability to conform to any irregularities in the surfaces being sealed.

The oval design is particularly effective in applications where high pressures and temperatures are involved, as it maintains its sealing ability without compromising integrity. A rectangular or square cross-section may not offer the same level of flexibility and adaptability required for effective sealing in dynamic environments. Therefore, recognizing that ring gaskets are oval in cross-section is crucial for understanding their function and effectiveness in refrigeration and other industrial systems.
