1. A push-to-connect and quick-release coupling socket comprising:
a socket body extending between first and second socket faces, the socket body comprising a first shelf stop and a collar movably coupled along the socket body between a locked coupling configuration and an unlocked configuration, wherein the first socket face is configured to receive a plug;
a plug receiver at least partially inside the socket body and slidable axially relative to the socket body, wherein a first end of the plug receiver is configured to couple with a dispenser tip of the plug, and wherein a second end of the plug receiver is configured to dispense flowable material received from the plug, the plug receiver comprising:
an axial inner passage configured to receive the flowable material from the plug and release the material at the second end of the plug receiver;
a first outer wall portion extending along a first length of the plug receiver and having a first radial dimension;
a second outer wall portion extending along a second length of the plug receiver and having a greater second radial dimension;
wherein the second outer wall portion is configured to bias the locking element toward the collar when the collar is in the unlocked configuration;
a first shelf between the first and second outer wall portions of the plug receiver;
wherein a travel of the plug receiver along an axis of the socket body is limited in a first direction by engagement of the first shelf and the first shelf stop; and
when in the unlocked configuration, the first end of the plug receiver is distal to the second socket face, and a locking element is unbiased by the collar; and
when in the locked-coupling configuration, the first end of the plug receiver is proximal to the second socket face, and the collar biases the locking element toward a lock receiver of the plug.
