The indicated minimum application temperatures are thought as a general guideline because a seals function at lower temperatures is dependent on the kind of the seal.the general application conditions, and on the kind of the surrounding metal parts the seal is in touch with.The indicated upper-temperature limits may be exceeded, but this reduces the service life.Other materials available on request.
