[1] So that they may make proper contact with its valve seat. Along with a corresponding valve spring, they are one component of an engine’s valve train.
O-ring mounting for an ultra-high vacuum application. [11] Pressure distribution within the cross-section of the O-ring. The orange lines are hard surfaces, which apply high pressure. The fluid in the seams has lower pressure. The soft O-ring bridges the pressure over the seams. O-rings are available in various metric and inch standard sizes.
