Abstract
In a fluid face seal assembly comprising an elastomeric annular seal for engaging in a recess of a stationary housing or the like component, an axially directed extension on a radially inner limb of the annular seal, an annular face seal carried by said extension and spring means acting between said face seal and said annular seal to maintain a resilient relationship between the two, the invention provides a step constituting a carrier member at the free end of the extension and a thickened free end on the step which retains the face seal in abutment against the shoulder between the step and the remainder of the extension, and a retainer acting to compress the thickened end of the step between itself and a radially adjacent part of the face seal thereby mechanically to lock said face seal onto said carrier member.
