Cummins Rectangular Strip Seal (Part 4325565) in Nissan Engines

The Cummins Rectangular Strip Seal, identified by part number 4325565, is a component in various Nissan engines, including the ISV series. This seal is designed to provide a reliable barrier against fluid leaks, ensuring the engine’s internal components remain protected from contaminants and maintain optimal performance.

Application in Nissan ISV Engines

In the Nissan ISV engines, the Rectangular Strip Seal is strategically placed to manage the flow of fluids, particularly in areas where moving parts interface with stationary components. This seal’s design allows it to conform to the contours of engine parts, creating a tight seal that prevents oil, coolant, or other fluids from escaping.

The seal’s placement is crucial in maintaining the integrity of the engine’s lubrication and cooling systems. By preventing leaks, the seal helps to maintain consistent pressure and temperature levels, which are essential for the engine’s longevity and efficiency.

Importance of the Seal

The Rectangular Strip Seal’s role in the engine’s operation cannot be overstated. Its ability to withstand high temperatures and pressures ensures that it remains effective even under the most demanding conditions. This reliability is vital for the overall performance and durability of the engine.

Role of Part 4325565 Rectangular Strip Seal in Engine Systems

The 4325565 Rectangular Strip Seal is a component in ensuring the efficient operation of various engine systems. Its primary function is to provide a reliable seal in areas where components connect or interface, preventing leaks and maintaining system integrity.

Air Intake Connection

In the air intake connection, the 4325565 Rectangular Strip Seal ensures a tight seal between the air intake and the engine block. This seal is vital for maintaining the correct air-fuel ratio, which is necessary for optimal combustion efficiency and engine performance.

Exhaust Recirculation Valve Kit

When integrated into the exhaust recirculation valve kit, the seal helps in managing the flow of exhaust gases that are recirculated back into the intake tract. This process reduces nitrogen oxides (NOx) emissions and improves fuel efficiency. The seal prevents any unwanted leaks, ensuring that the recirculated gases are effectively managed.

Fuel Pump Kit

In the fuel pump kit, the 4325565 Rectangular Strip Seal is used to create a secure connection between the fuel pump and the fuel lines. This ensures that fuel is delivered to the engine under the correct pressure and without any leaks, which is essential for consistent engine performance and safety.

Gasket Kit

Within a gasket kit, this seal plays a role in ensuring that all mating surfaces between engine components are properly sealed. This is particularly important in maintaining the integrity of the combustion chamber, preventing any gas or fluid leaks that could lead to engine damage or reduced efficiency.

Long Block Kit

In a long block kit, the seal is used to ensure that all connections within the engine block assembly are secure. This includes seals between the cylinder heads, intake manifold, and other critical components, ensuring that the engine operates smoothly and efficiently.

Service Kit

When included in a service kit, the 4325565 Rectangular Strip Seal is often used to replace worn or damaged seals during routine maintenance. This helps in restoring the engine’s performance to its optimal level by ensuring all connections are leak-free.

Turbocharger Kit

In a turbocharger kit, the seal is used to ensure that the turbocharger’s connections to the engine are secure. This is important for maintaining the boost pressure and preventing any leaks that could reduce the turbocharger’s efficiency and the engine’s overall performance.
