Spring lip seals have been used for many years. Spring lip seals are used in a manner similar to conventional elastomer seals, such as o-rings. Elastomer seals often fail due to conditions that often occur in their operating environment, such as chemical corrosion, extreme high or low temperatures, extrusion, friction, or compression set. However, spring lip seals have different structures and do ...
