The outer diameter (OD) of a flat ring gasket is equivalent to which measurement?

The outer diameter (OD) of a flat ring gasket is equivalent to the overall diameter of the flange. This is because the gasket is designed to fit between the flanges of two connected pipes or components, creating a seal that prevents leakage. The OD of the gasket specifically needs to match the outer profile of the flange to ensure an effective seal.

When installing a gasket, it's crucial that it aligns properly with the flanges to avoid any misalignment that could lead to leaks. Understanding the dimensions of the gasket and the flanges is vital for ensuring the integrity of the piping system. Hence, recognizing the outer diameter of the gasket as essential for fitting correctly within the overall diameter of the flange reinforces the importance of accurate measurements in pipe fitting.
