Sealing Fundamentals

When fluid pressure is applied, it causes additional internal stress, which supplements the preload and consequently prevents leakage An example of this phenomenon is illustrated in Figure 1 below by a Finite Element Analysis (FEA) simulation performed on an o-ring Figure 1 - Finite Element Analysis (FEA) simulation performed on an O-ring.
