A static rubber sealing ring for sealing against fluids that have high temperatures and/or that are under high pressures, particularly for sealing between a cylinder lining and a cylinder block of internal combustion engines. With the intention of providing such a sealing ring that can advantageously replace the O-ring, particularly in such vibrating apparatus as piston engines, particularly diesel engines, there is proposed a sealing ring which includes a radially inner sealing surface (12) which is generally circular-cylindrical in shape at least when the sealing ring is fitted, and a pair of generally mutually parallel and axially opposing flat side surfaces (16), each of which extends generally at right angles to the radially inner sealing surface so as to define an edge (14) together therewith, and each of which connects with a gently rounded, radially outer sealing surface (22) of the ring via a transition surface (18, 20).

A static rubber sealing ring for sealing against fluids having high temperatures or under high pressures, comprising a radially inner sealing surface which is generally circular-cylindrical in shape in a non-fitted state of the ring, a pair of substantially mutually parallel and axially opposing flat side surfaces, each flat side surface extending generally at right angles to the radially inner sealing surface such as to define an edge together with said sealing surface, and each flat side surface being connected to a gently rounded radially outer sealing surface of the ring via a transition surface, each transition surface, as seen in the cross-section of the ring, being comprised of a radially inner concave contour having a small radius of curvature and narrowing the ring in a radially outward direction, and a radially outer rectilinear contour which, in a direction towards, the outer sealing surface, is inclined to a radial center plane of the sealing ring.
