A cap and Luer connector arrangement with an improved external seal is provided for a fluid transfer connector or fitting that has a nozzle (30) wi th a surrounding annular collar (36) located coaxially within a surrounding sealing lip (50). The cap (10) includes a structure of resilient material which defines an end wall (20), an annular, inner sleeve (150) extending fro m the end wall (20), and an annular, outer skirt (24) extending from the end wall (20) to define an annular receiving channel between the outer skirt (24 ) and the inner sleeve (150). At least a portion of the inner sleeve (150) has an inner surface (172) for sealingly engaging the nozzle (30). A distal end of the outer skirt (24) includes a seal region having a V-shaped cross-sectiona l crevice (206). The Luer connector sealing lip (50) and seal region are distorted when the sealing lip (50) is received into the crevice (206) durin g initial screwed-on installation of the cap (10) to the Luer connector, formi ng an external seal. The sealing lip (50) and seal region are heat set during autoclave-sterilization of the cap (10) and Luer connector arrangement, whic h prevents reinstallation of the cap once removed.
