Abstract
A seal assembly for sealing between first and second tubular members includes an annular seal body disposeable within an annular gland between the tubular members and formed of a generally compressible polymeric material. The seal body has a first axial sealing surface disposed against a first tubular member end surface, a second axial sealing member disposeable against a second tubular member end surface and a recess(es) defined partially by an angled activation surface. An annular backing ring formed of a substantially rigid material is disposed the body recess to couple the backing ring with the seal body. The backing ring has an outer axial end disposeable against the first member end surface to prevent radially outward displacement of the portions of the seal at the first member end surface and is biased axially toward the first member end surface when compression of the seal body displaces the activation surface axially.
