O-rings are designed to contain thousands of pounds of pressure by creating a seal between two or more parts. O-ring measurements are defined by the inside diameter and the thickness. rnrnThere are many causes for O-Ring failure, such as pressure, friction, temperature or chemicals. The most common are: • Extrusion and Nibbling...Read moreu> - O-ring has ragged, tattered edges. These are commonly caused by pressure spikes which shear off tiny "bites" from the o-ring, or caused by clearance gaps. • Abrasion - One or both sides of the o-ring appear rough and slightly flattened. Commonly caused by a contact surface that is too rough, contains grit or is too smooth to allow lubrication. • Over Compression - O-ring is flattened on both sides and may have a "ring" split along its length. Commonly caused by excessive pressure or heat. • Heat Hardening - O-ring has a pitted or cracked surface, and often is flattened on both sides. Caused by temperature exceeding o-ring capacity. • Weather/Ozone Cracking - O-ring is covered in small surface cracks. Caused by exposure to ozone, UV rays and air pollution. Excessive seal stretching causes similar cracking.
