ABSTRACT:
A seal for being mounted on a reciprocating machine part to seal the machine part includes a sealing element made of elastomer material. The sealing element has a sealing lip defined by two surfaces that intersect at a sealing edge for resting in a sealing manner against the outer surface of the machine part. One of the two surfaces includes a first section and a second section. The first section is inclined at a first angle of inclination with respect to the central axis of the sealing element while the second section is inclined at a second angle of inclination with respect to the central axis of the sealing element, and with the first and second angles of inclination being different from one another.
