A mechanical face seal comprises a seat associated with one of a pair of relatively rotatable components and a seal face member associated with the other component and movable axially with respect thereto. Said seal face member has a sealing face which engages an opposed face of the seat to provide a seal therebetween, and an integral secondary sealing means remote from said face. Means is provided to urge the seal face member axially into sealing engagement with the seat and the secondary sealing means radially into sealing engagement with the component associated with the seal face member.
