1. A quick connect fluid connector swivel, comprising:
a first portion that is mechanically and fluidly connectable to a first fluid system;
a second portion that is mechanically and fluidly connectable to a quick connect fluid connector that is connectable to a second fluid system;
a fluid passageway that fluidly connects the first portion and the second portion to permit fluid communication between the first fluid system and the second fluid system via the quick connect fluid connector; and
the first portion and the second portion are rotatable relative to one another about a longitudinal axis;
the first portion is a housing with a port that is mechanically and fluidly connectable to the first fluid system;
the second portion is a shaft that is disposed within the housing, an end of the shaft is mechanically connectable to the quick connect fluid connector, and the shaft includes at least a portion of the fluid passageway;
the housing has a housing first end, a housing second end, and the longitudinal axis extends from the housing first end to the housing second end;
a housing passageway formed in the housing along the longitudinal axis, the housing passageway extending through the housing first end;
the port is in fluid communication with the housing passageway;
the shaft is disposed in the housing passageway, the shaft having a shaft first end, a shaft second end, and a shaft axis that is coaxial to the longitudinal axis;
the shaft first end is connectable to the quick connect fluid connector;
the shaft is rotatable relative to the housing about the shaft axis, and the shaft is longitudinally displaceable relative to the housing in a direction parallel to the shaft axis;
a first stop that limits longitudinal displacement of the shaft relative to the housing in a first longitudinal direction and a second stop that limits longitudinal displacement of the shaft relative to the housing in a second longitudinal direction;
the fluid passageway includes a shaft fluid passageway formed in the shaft along the shaft axis and extending from the shaft first end in a direction toward the shaft second end, the shaft fluid passageway is in fluid communication with the port;
wherein the housing first end includes a first removable cap threaded thereon, and the housing second end includes a second removable cap threaded thereon; and
the shaft first end extends beyond the first removable cap.
