Role of Part 3081964 Tube Nut in Engine Systems

This part is integral to the secure and efficient operation of various engine components. It facilitates the connection and sealing of multiple tubes and hoses, ensuring the proper flow of fluids and gases throughout the engine system.

In the compressor coolant arrangement, the Tube Nut ensures a tight seal between the compressor and the coolant tubes, maintaining the optimal temperature of the compressor and enhancing its performance.

Within the crankcase breather system, it connects the breather tube to the crankcase, allowing for the safe release of pressure and contaminants from the crankcase without compromising the engine’s integrity.

For the fuel control module and associated fuel plumbing, the Tube Nut plays a key role in connecting the fuel supply tube and fuel transfer tube. This ensures a consistent and reliable fuel delivery to the engine, which is essential for smooth operation.

In the lubricating oil system, the Tube Nut is used to connect the lubricating oil drain tube, facilitating the efficient drainage of used oil and the introduction of fresh lubricant.

The Tube Nut is also vital in the turbocharger plumbing. It secures connections in the turbocharger coolant supply tube, turbocharger coolant drain tube, and pressure sensing tube. This ensures that the turbocharger operates within safe temperature ranges and that pressure readings are accurate for engine management.

Additionally, in the water management system of the engine, the Tube Nut is employed in the water inlet tube, water outlet tube, and water transfer tube connections. It ensures that coolant flows smoothly through the engine, aiding in temperature regulation.

The Tube Nut also supports the connection of the water inlet tube mounting, providing a stable and leak-free attachment point for the water inlet tube to the engine block or head.

Lastly, for components requiring an alternative or flexible hose connection, such as in the air intake or exhaust systems, the Tube Nut allows for a secure yet adaptable join, accommodating the dynamic movements and thermal expansions of these systems.
