A sealing mechanism for a customer replaceable unit (CRU) within a computer system is provided. The sealing mechanism comprises a faceplate for the CRU, wherein insertion and extraction latches are recessed into a trench within that faceplate. The backside of the faceplate has a protruding rim around the perimeter. The rim engages a groove in the subsystem enclosure, which surrounds the aperture that the CRU engages. Since the faceplate incorporates a perimeter ridge and a trench structure, the interacting groove follows the contour of the trench. Thus the rim and groove both trace the faceplate trench around the faceplate. The groove in the subsystem enclosure has an entrenched section at both ends of the receptacle perimeter that accommodate sections of the faceplate rim that trace the trench in the faceplate. A compliant seal material seated is in the groove of the chassis-mating surface, wherein the seal material follows the contours of the chassis-mating surface and ensures electrical contact between the chassis-mating surface and protruding faceplate rim.
