Abstract
Abstract Sealing elements and method for their assembly wherein the assembly comprises a first element having a body with at least one projection fixed thereto, wherein the projection is formed of a material which is deformable and which has an elastic memory, and a second element having at least one groove therein which is adapted to receive the projection of the first element whereby said projection is urged toward a sealing relation with the groove in response to the combination of forces generated by the elastic memory of the projection and by the internal pressures exerted on the sealing elements.
