In this edition, we’ll discuss the causes and signs of extrusion damage, as well as potential solutions and methods for prevention. Extrusion damage failures often occur in dynamic applications such as hydraulic controlled rod and piston seals. These can also occur in static applications when seals are subjected to high-pressure pulsing, especially when the gland extrusion gaps are excessive.

When an O-ring is under high-pressure gas for an extended period of time, and that pressure is reduced too rapidly, explosive decompression can occur. The gas that gets trapped or absorbed in the O-ring’s micropores causes splits or ruptures in the surface of the O-ring.
