An adapter seal for use with conduit fittings having a first part having a conical nose of given axial dimension, a second part having a recessed conical surface in axial alignment with the nose and complementary thereto, and connection means axially displacing the nose and conical surface toward each other, in combination, an annular metal seal having a substantially cylindrical circumferential portion, a cone portion depending from said circumferential portion having an axial dimension slightly less than the first part nose axial dimension and having inner and outer parallel sides defining the cone portion radial thickness and terminating in an inner end, and an annular elastomer seal of conical form bonded to said cone portion inner end constituting an extension of said seal cone portion and the conical configuration thereof whereby compression of said cone portion and elastomer seal between the fitting nose and conical surface establishes both a metal-to-metal seal and an elastomer seal.
