O-rings are made to contain thousands of PSI pressure by creating a seal between two or more parts. O-ring measurements are defined by the inside diameter and the thickness. There are many causes for O-ring failure. The most common among power tools are: • The O-ring has ragged, tattered edges. These are commonly caused by pressure ...Read morespikes which shear off tiny "bites" from the O-ring, or caused by clearance gaps. • 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. • The O-ring is flattened on both sides and may have a "ring" split along its length. Commonly caused by excessive pressure or heat. • The O-ring has a pitted or cracked surface, and is often flattened on both sides. Caused by temperature exceeding O-ring capacity. • The O-ring is covered in small surface cracks. Caused by exposure to ozone, UV rays, and air pollution. Excessive seal stretching (greater than 5%) causes similar cracking.
