An embodiment includes a rapid-connect coupler including a coupler body configured to convey a fluid; a coupling head at a first end of and communicating with the coupler body, the coupling head configured to transition between a coupled configuration and a de-coupled configuration. The coupler may further include a stop apparatus configured to allow the coupling head to transition from the de-coupled configuration to the coupled configuration without obstruction, and the stop apparatus may be configured to provide a hard-stop as the coupling head transitions from the coupled configuration to the de-coupled configuration.
