An apertured flange member with a beveled inner edge slidably disposed about a uniform cylindrical surface of a tubular member having an elongated axial bore and a circumferential recess immediately adjacent the tube's end extremity in which recess a resilient sealing ring is seated, and means for moving the flange member toward a second body arrangement to produce a fluid-tight (liquid or gas) communication between the bore and an opening in an end extremity of the second body arrangement by the action of the beveled edge urging only a portion of the sealing ring beyond its seat and toward and contacting the second body arrangement, whereby the sealing ring is compressed into an inescapable cavity formed by the beveled edge of the flange and the circumferential recess.
