Abstract

Elastic sealing ring for sealing between a displaceable and/or rotatable component, such as a piston (2), piston rod (3), shaft etc., and a surrounding component, such as a cylinder block (1), a cylinder end wall etc. The sealing ring is adapted so as to be mounted in a groove in one component and has at least one sealing surface (28; 31, 32) intended for bearing against the other component, and comprises two materials with different properties. The sealing ring is made with an inner injection-molded core (17) made of a first material with first properties and an outer layer (18) made of a second material with in part second properties and injection-molded together with the core. This material is fused together with the material in the core in the boundary zone. The sealing surface is at least partly formed by a part of the outer layer (18), which has lower friction on contact with a component part bearing against it than the material in the core (17). The invention also relates to a method for manufacturing a sealing ring as above.
