A sealing ring for sealing a second component, which rotates in relation to a first component, for example for sealing a distribution channel of a rotary media distributor in a beverage filling system is described. The sealing ring includes an annular seal main body to be accommodated on the first component and a wear profiled element arranged radially within the seal main body for contacting the second component in a sealing manner, wherein the seal main body has at least one region of reduced radius in order to enable deformation of the seal main body as the seal main body is assembled with the first component.
