Zusammenfassung:	Methods and apparatus for estimating useful life of a seal in a process control device are disclosed. An example apparatus includes a processor to: determine a plurality of operational cycles of a stem or shaft of a process control device; determine a first value corresponding to a stress experienced by the seal for each of the operational cycles; and estimate a total amount of useful life of the seal consumed based on each of the first values; and a database to store data associated with the total amount of useful life of the seal consumed.
