Описание: In some instances, O-ring extrusion damage is described as “nibbling,” where small pieces are torn away from the seal. Nibbling typically occurs as the result of pressure fluctuations in the system; increased pressure creates a larger clearance gap, allowing the seal to extrude. After the pressure reduces, the seal returns to its original shape, but small pieces are eroded away as the seal escapes the gap. As the cycles continue, nibbling repeats and the seal eventually fails.
