Role of Part 3393586 O-Ring Seal in Engine Systems

This part is integral to maintaining the integrity and efficiency of various engine systems. It ensures that components operate within optimal parameters by preventing leaks and maintaining pressure. Here’s how it interfaces with specific components:

Centrifuge Cover Kit

In the centrifuge cover kit, the O-Ring Seal is positioned to create a tight seal around the centrifuge housing. This prevents contaminants from entering the system and ensures that the centrifuge operates efficiently by maintaining a consistent internal environment.

Filters

For both full flow oil filters and lubricating oil filters, the O-Ring Seal is essential in securing the filter to its housing. This seal prevents oil bypass, ensuring that the filtration process is effective and that clean oil is consistently circulated through the engine.

Lubricating Oil Filter Kit

Within the lubricating oil filter kit, the O-Ring Seal plays a role in connecting the filter to the filter head. This connection is vital for maintaining the pressure differential required for efficient oil filtration, thereby prolonging the life of the engine components.

Lubricating Oil Filter Head

The seal is also crucial in the lubricating oil filter head, where it ensures that the filter media is properly seated. This seating is necessary for the filter to perform its function without allowing unfiltered oil to pass through.

Oil Cooler Repair Kit

In the oil cooler repair kit, the O-Ring Seal is used to ensure that the connections between the cooler and the engine’s oil lines are leak-free. This is important for maintaining the efficiency of the cooling process, which is essential for engine longevity.

Seal Kit

The seal kit often includes multiple O-Ring Seals designed to fit various components throughout the engine system. These seals are used to prevent fluid leaks and maintain pressure in systems such as the fuel injection, hydraulic, and lubrication systems.

By ensuring these seals are intact and properly installed, engineers and mechanics can significantly enhance the reliability and performance of engine systems ².

Conclusion

The Cummins 3393586 O-Ring Seal is a vital component in the maintenance and efficiency of commercial truck engines.
