There is provided an organopolysiloxane composition having low compression set as well as fuel and oil resistance in addition to high strength, good elongation, and tear comprising: (A) 100 parts of a first component comprising: (1) a vinyl-containing liquid organopolysiloxane or a blend of vinyl-containing liquid polysiloxanes; (2) optionally, filler; and (3) a catalyst; and (B) from 1 to 100 parts, based on 100 parts of (A), of a hydrogen silicone composition selected from the class consisting of hydrogen containing silanes and hydrogen containing polysiloxanes and mixtures of hydrogen containing polysiloxanes with fillers and high viscosity polysiloxanes; (C) optionally, magnesium oxide to impart oil resistance; (D) optionally, an MQ resin to impart fuel resistance; and (E) optionally, a cerium containing compound or, alternatively, tetramethyldivinyldisilazane to impart low compression set.
