An improved sealable connector has a geometry which effects reliable sealing upon assembly. The connector is useful, for example, for connecting a pressure sensor to a fuel pump accumulator in a fuel injection system. The connector includes a male member, a female member, and an annular seal disc which compressibly seats between the male and female members. The male member has a tip with a flat annulus at an innermost radius surrounding a fluid-delivery bore. A frustoconical section of the tip extends radially outwardly from the annulus, sloping away from the plane of the annulus at about 5.degree.-15.degree., for example. The female member has a cavity shaped to receive the male member, the cavity having a bottom defined by a flat annular seat surrounding another fluid-delivery bore. The seal disc is compressed between the flat seat of the female cavity and the planar/frustoconical tip of the male member. Axial compressive loads on the disc are concentrated under the planar annulus such that the disc has a radially-inward zone of plastic compression adjacent to the fluid-carrying bore, this plastic compression zone being radially-outwardly surrounded by an elastic compression zone.

[ What is claimed is:] [1.] A sealable fluid connector comprising:a male connector member including:a cylindrical body with a first bore disposed longitudinally therein, said body having a tip with a planar annulus at a radially innermost portion of said tip and surrounding an opening to said first bore, and said body having a frustoconical section sloping radially outwardly from said planar annulus;a female connector member including a cavity for receiving said male connector member with a complementarily threaded engagement, an end of said cavity is defined by a planar annular seat which is parallel to said planar annulus when said male connector member is inserted, said seat surrounding a second bore disposed in said female connector member; andan annular seal disc compressibly seatable between said planar annulus and said planar seat to seal between said male and female members and to permit fluid communication between said first and second bores, whereby when said male connector member is matably received in said cavity, said seal disc is caused to have a radially-inward plastic compression zone radially-outwardly surrounded by a gradually-decreasing elastic compression zone.
