<p>A connector for use in an ultra-high vacuum system that has a metal conduit section (30) with a first hardness, a metal fitting member (60) with a second hardness greater than the first hardness of the conduit section, and a metallic reaction-inhibiting barrier (80) positioned between the conduit section and the fitting member to sealingly attach the conduit section and fitting member together. The metal conduit section has a first end (31), a second end (33), and a flow path between the first and second ends. The metal fitting member (60) has a rear face (61) proximate to the second end of the conduit section, a front face (63) facing away from the rear face, and an opening between the front and rear faces aligned with the flow path (F) of the conduit section. The reaction-inhibiting member (80) also has an aperture aligned with the flow path of the conduit section and the opening of the fitting member. The reaction-inhibiting member is selected from a group of metals that will substantially inhibit metallic and chemical interaction between the conduit section and the fitting member. Accordingly, the reaction-inhibiting barrier prevents the joint between the metal conduit section and the metal fitting member from deteriorating and causing leaks under ultra-high vacuum and temperature cycling conditions.</p> |
