640-2379: 4.57mm Inner Diameter Air Tube Assembly

An Air Tube Assembly is used in the air starting lines to supply compressed air to start an engine. It consists of a tube assembly with a flared connector, swivel nut, and an O-Ring Face Seal (ORFS) sleeve. This assembly connects with a hose and connector, enabling the transfer of compressed air to the engine for starting purposes. These tubes are often bent and routed to fit within the available space in the cylinder block cover and provide an efficient flow of air. It has an optimum size that allows more air to flow through the tube along with maintaining the velocity of the flow. Attributes: • Provided with a flared connector and ORFS sleeve to create a tight and reliable seal between the tube assembly and the hose connector, preventing any loss of compressed air • Withstands a working pressure of 1000 kPa and a minimum burst pressure of 4000 kPa without encountering excessive turbulence or pressure drops • Includes a swivel nut that enables the assembly to rotate freely, facilitating proper alignment and connection with other fittings, ensuring a leak-free connection Applications: An Air Tube Assembly serves as a conduit for the transfer of high-pressure air, allowing for the controlled and efficient delivery of compressed air to the engine's starting unit. It connects with a hose and connector, providing the necessary air supply to initiate engine start-up.
