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.
WARNING: Proposition 65 Warning for California Residents View Details
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
