Role of Part 4940183 Male Union in Engine Systems

The 4940183 Male Union is an essential component in the integration and functionality of various engine systems. Its primary role is to facilitate secure and leak-proof connections between different plumbing and accessory components.

In the context of an aftermarket turbocharger, the Male Union ensures that the turbocharger plumbing is correctly and firmly attached, allowing for efficient flow of air and fluids. This is particularly important in the compressor section where air intake and pressure regulation are vital.

When dealing with heat exchangers such as the Core Assembly Heat Exchanger35, Core Assembly Heat Exchanger35w, and Core Assembly Hy35w, the Male Union plays a significant role in connecting the turbocharger coolant plumbing. This ensures that the coolant circulates effectively, maintaining optimal temperatures and preventing overheating.

In the turbocharger core and turbocharger gasket kit, the Male Union aids in creating a robust connection that can withstand high pressures and temperatures. This is essential for the durability and performance of the turbocharger.

For the drive and rear gear train accessory, the Male Union is used in the turbocharger oil plumbing to ensure that oil is delivered consistently and under the right pressure to lubricate moving parts, reducing wear and enhancing efficiency.

The engine mounting and long block also benefit from the secure connections provided by the Male Union. In these applications, it ensures that all plumbing components, whether for air, coolant, or oil, are reliably connected, contributing to the overall stability and performance of the engine.

Conclusion

In summary, the 4940183 Male Union is a versatile component that enhances the functionality and reliability of various engine systems by providing secure and efficient connections. Its robust design and precise engineering make it an essential component for maintaining the integrity of the engine’s systems.
