O-rings are made to contain thousands of PSI pressure by creating a seal between two or more parts. O-ring measurements are specified by the inside diameter and the thickness.
Of the many causes for O-Ring failure, the most common among power tools are:
• Extrusion and Nibbling – 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.
