ABSTRACT:
An improved seal for sealing across an annulus between an inner cylindrical sealing surface and an outer cylindrical sealing surface. The seal provides a body and a flange spaced therefrom with an annular flexible arch extending between the body and the flange and having a taper of its thickness so that its thinnest section is at the mid point of the arch and within its sealing area. A suitable sealing is provided to seal against the surface opposite to the surface against which the flexible annular arch seals so that there is a complete sealing across the annulus. This seal is suitable for piston rod sealing, valve stem sealing and for sealing in the annulus between two tubular well members.
