Abstract: A quick connect coupling is disclosed for use with a tubular conduit having a radially outwardly extending bead adjacent a free end of the tubing. The coupling includes an elongated tubular and cylindrical housing having an axial passageway formed through it which forms a fluid passageway and is open at both ends. One end of the housing has a enlarged diameter internal bore portion adapted to axially receive the free end of the conduit including the conduit bead as the conduit is inserted to a magnet position. A retainer within the internal bore portion of the housing lockingly engages the conduit bead when the conduit is moved to its connected position while fluid seals engage the outer periphery of the conduit. A one way valve is also contained within the housing passageway which permits fluid flow in only one direction through the housing passageway.

Abstract: A quick connect coupling is disclosed of the type adapted for connection to a nipple having a radially inwardly extending recess formed at a position spaced from a free end of the nipple. The quick connect coupling includes a tubular and cylindrical body open at each end wherein one end of the body is dimensioned to slidably extend over the free end of the nipple to a connected position. The body includes a plurality of circumferentially spaced openings which are in alignment with the nipple recess when the coupling is moved to its connected position. A spherical retainer is disposed in each opening and is radially movable between a locked and an unlocked position. A tubular and cylindrical locking ring normally urges the retainers to their locked position. Each housing opening has at least one side wall which extends substantially perpendicular from a predetermined diameter of the body. This enables the body to be molded from a two-part mold without the necessity of insert molding.
