This type of O-ring failure is caused when the seal becomes \u201chung-up\u2019\u2019 at one point on its diameter (against the cylinder wall) and slides and rolls at the same time. The resultant twisting of the O-ring as the sealed device is cycled finally causes the seal to develop a series of deep spiral cuts (usually at a 45\u00b0 angle) on the surface of the seal.[\/vc_column_text][\/vc_column][\/vc_row][vc_row margin_top=&#8221;0&#8243;
