An expendable adaptor for quick coupling flexible hoses to a variety of devices such as oxygen breathing equipment and including an enlarged deformable head portion having at least a pair of concentric sleeves the inner of which is axially recessed so that its forward face engages an end edge of a complementary coupling fitting in sealing relationship while the outer sleeve surrounds the fitting in a secondary sealing as well as anchoring relationship.

A universal adaptor for selectively coupling flexible tubing to equipment having male fittings of at least two different outside diameters, the larger of which has a threaded exterior surface, the invention comprising: a body portion having an inner end apertured to receive a flexible tube; an enlarged outer end having a soft radially outwardly deformable hollow section having substantially cylindrical inside diameter to grip the exterior threaded surface of the male fitting thereof to establish resistance against axial movement; and a coaxial inner hollow substantially cylindrical section integral with the outer section and formed of relatively soft deformable material having a hardness rating in the range of 40 to 85 durometers, the forward end of the inner section being contained in a plane perpendicular to the axis of the outer cylindrical section and recessed with respect to the forward end of the outer section and adapted to be engaged by a forwardly facing portion of the larger male fitting to deform when engaged thereby to form a seal therewith which is maintained by the resistance against axial movement of the adaptor on the fitting as established by the outer section, said inner section having an inside diameter slightly smaller than the outside diameter of the smaller male fitting and adapted to be entered by the smaller male fitting to deform radially outwardly in sealing relationship therewith.
