Role of Part 3393569 O-Ring Seal in Engine Systems

The 3393569 O-Ring Seal is instrumental in ensuring the integrity and efficiency of various engine systems by providing essential sealing functions. In the context of a full flow oil filter, this part is positioned to create a tight seal between the filter and the engine block or filter housing. This seal prevents oil leaks and maintains consistent oil pressure, which is vital for the lubrication of engine components.

When integrated into a lubricating oil filter, the O-Ring Seal ensures that the filter media is securely contained, allowing for effective filtration of contaminants from the oil without any bypass. This contributes to the longevity and performance of the engine by ensuring that only clean oil circulates through the system.

In a filter housing kit, the O-Ring Seal plays a significant role in assembling the components together. It ensures that the housing is leak-proof, which is essential for maintaining the structural integrity of the filtration system and preventing oil loss.

For the lubricating oil filter head, the O-Ring Seal is used to seal the connection between the filter head and the engine or the filter housing. This seal is important for maintaining the pressure differential required for efficient filtration and to prevent any oil from escaping.

Lastly, in a lubricating oil filter kit, the O-Ring Seal is a key component that ensures all parts of the kit—filter, housing, and head—are properly sealed. This comprehensive sealing is essential for the overall effectiveness of the lubrication system, ensuring that the engine receives clean, pressurized oil for optimal performance and durability.
