A tire inflation system comprising: a tube assembly that provides pressurized gas to a tire, wherein the tube assembly includes: a tube having a first end and a second end; a first fitting that is disposed proximate the first end of the tube, wherein the first fitting has a first port that receives pressurized gas, a second port that provides pressurized gas to the tube, and a third port that is fluidly connected to the first port; a second fitting that is disposed proximate the second end of the tube and is coupled to a tire valve of the tire; and a pressure relief valve that is fluidly connected to the third port of the first fitting, wherein the pressure relief valve vents pressurized gas from the tire when a pressure of the pressurized gas in the tire exceeds a threshold pressure; and an intermediate valve characterized in that: the intermediate valve is disposed between the first port and the pressure relief valve, the intermediate valve closes to inhibit pressurized gas from flowing through the third port when the pressure relief valve is removed from the intermediate valve, and the intermediate valve opens to permit pressurized gas to flow through the third port when the pressure relief valve is mounted on the intermediate valve. a tube assembly that provides pressurized gas to a tire, wherein the tube assembly includes: a tube having a first end and a second end; a first fitting that is disposed proximate the first end of the tube, wherein the first fitting has a first port that receives pressurized gas, a second port that provides pressurized gas to the tube, and a third port that is fluidly connected to the first port; a second fitting that is disposed proximate the second end of the tube and is coupled to a tire valve of the tire; and a pressure relief valve that is fluidly connected to the third port of the first fitting, wherein the pressure relief valve vents pressurized gas from the tire when a pressure of the pressurized gas in the tire exceeds a threshold pressure; and an intermediate valve characterized in that: the intermediate valve is disposed between the first port and the pressure relief valve, the intermediate valve closes to inhibit pressurized gas from flowing through the third port when the pressure relief valve is removed from the intermediate valve, and the intermediate valve opens to permit pressurized gas to flow through the third port when the pressure relief valve is mounted on the intermediate valve. a tube having a first end and a second end; a first fitting that is disposed proximate the first end of the tube, wherein the first fitting has a first port that receives pressurized gas, a second port that provides pressurized gas to the tube, and a third port that is fluidly connected to the first port; a second fitting that is disposed proximate the second end of the tube and is coupled to a tire valve of the tire; and a pressure relief valve that is fluidly connected to the third port of the first fitting, wherein the pressure relief valve vents pressurized gas from the tire when a pressure of the pressurized gas in the tire exceeds a threshold pressure; and an intermediate valve characterized in that: the intermediate valve is disposed between the first port and the pressure relief valve, the intermediate valve closes to inhibit pressurized gas from flowing through the third port when the pressure relief valve is removed from the intermediate valve, and the intermediate valve opens to permit pressurized gas to flow through the third port when the pressure relief valve is mounted on the intermediate valve. the intermediate valve is disposed between the first port and the pressure relief valve, the intermediate valve closes to inhibit pressurized gas from flowing through the third port when the pressure relief valve is removed from the intermediate valve, and the intermediate valve opens to permit pressurized gas to flow through the third port when the pressure relief valve is mounted on the intermediate valve.
