Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

Although incidental food additives are generally considered safe at low levels, concerns arise regarding long-term exposure and cumulative effects. For example, pesticides used in agriculture can leave residues on fruits and vegetables, which, if not properly managed, might pose health risks over time. Similarly, heavy metals from processing equipment could lead to contamination if not effectively controlled.
