Question: 1 / 400

A metallic ring gasket is typically made from a material that is what compared to the flange material?

Harder

Equal

Softer

A metallic ring gasket is generally made from a material that is softer than the flange material. This design choice is intentional, as a softer gasket material can conform better to any irregularities in the flange surfaces, creating a tighter seal when compressed. The softer gasket material allows it to deform slightly under pressure, filling gaps and preventing leaks more effectively.

In contrast, if a gasket were made from a harder material, it might not compress adequately, leading to potential leakage due to insufficient sealing. The material properties of the gasket and flange work together to ensure effective sealing, and the relative softness of the gasket allows it to adapt to the conditions of service, enhancing reliability in the system.
