Sealing Stress - A Load Deflection (LD) curve is a Stress (MPa) vs. Strain (mm) curve. lt is the load required to compress a material at a destined thickness a determined deflection. lt is very useful when making material selections to meet engineering requirements such as flange load or controlled compression applications.

System Distortion - conformability is the ability of a gasket material to conform to flange surface roughness and out-of-flatness. At a given sealing stress a corresponding maximum allowable flange distortion assures that a “positive seal” is guaranteed for a defined material thickness.
