Role of Part 3072397 O Ring Seal in Engine Systems

This part is integral to maintaining the efficiency and reliability of various engine systems. Its application spans across multiple components, ensuring that each system operates within optimal parameters.

Compressor Coolant Arrangement

In the compressor coolant arrangement, the O Ring Seal is employed to create a tight seal between the compressor and the coolant passages. This ensures that coolant flows efficiently without leaks, maintaining the compressor’s temperature within safe operating limits. The seal prevents any coolant loss, which could lead to overheating and reduced compressor efficiency.

Corrosion Resistor Kit

When integrated into a corrosion resistor kit, the O Ring Seal plays a role in protecting metal surfaces from corrosive elements. By sealing off areas prone to corrosion, it helps maintain the integrity of the engine components, prolonging their lifespan and ensuring consistent performance.

Engine Oil Cooler

Within the engine oil cooler, the O Ring Seal is used to ensure that oil circulates through the cooler without any leaks. This is essential for dissipating heat from the engine oil, which in turn helps in maintaining optimal oil viscosity and preventing engine wear.

Lubricating Oil (Top Level Assembly) Cooler

In the lubricating oil (top level assembly) cooler, the O Ring Seal is critical for maintaining the seal between the cooler and the top-level assembly. This ensures that lubricating oil is effectively cooled before it is recirculated through the engine, reducing the risk of oil breakdown and enhancing lubrication efficiency.

Oil (Top Level Assembly) Cooler

Similarly, in the oil (top level assembly) cooler, the O Ring Seal ensures that oil is efficiently cooled without any leaks. This is vital for maintaining the oil’s properties, which are essential for reducing friction and wear within the engine.

Oil Cooler (Top Level Assembly) Lubricating

For the oil cooler (top level assembly) lubricating system, the O Ring Seal ensures that the lubricating oil is effectively cooled. This helps in preserving the oil’s lubricating properties, which are crucial for the smooth operation of engine components.

Particulate Trap System

In the particulate trap system, the O Ring Seal is used to ensure that exhaust gases are effectively filtered without any leaks. This is important for reducing emissions and maintaining the efficiency of the trap system.

Shutoff Valve

Finally, in the shutoff valve, the O Ring Seal ensures that the valve can effectively control the flow of fluids without any leaks. This is essential for the precise operation of the valve, which is often critical for the overall performance and safety of the engine system.

Conclusion

The Cummins Part #3072397 O Ring Seal is a critical component in ensuring the efficiency and reliability of commercial truck systems.
