Leakage can manifest in several ways, often pointing to specific failure causes. Nitrile rubber (NBR) is the most common material due to its excellent resistance to petroleum-based oils and fuels, making it ideal for gearboxes and hydraulic systems.

A dry, cracked lip indicates exposure to excessive heat or incompatible chemicals that have caused the material to deteriorate. The use of appropriate installation tools, such as seal drivers and mandrels, is necessary to ensure the seal is driven into place evenly without twisting or damage, which could compromise its sealing capability.
Diagnosing the specific pattern of wear allows for corrective action beyond simply replacing the seal. These seals typically feature a defined inner diameter, outer diameter, and cross-sectional size, all of which must align perfectly with the grooves and tolerances of the housing.
