Observe the special groove shape, and the bottom radius, as well as the metallic retainers lips that makes possible keep the O-Ring secured in the groove shape.

This lips magnified looks like small radius and they are also critical for a good seal to work, because they can ruin the O-Ring performance by marking to much the O-Ring surface, causing leakage, so the angles and radius are CRITICAL don't forget it.
