Role of Part 3631755 O-Ring Seal in Engine Systems

This part is instrumental in maintaining the integrity and efficiency of various engine systems. Its application spans across several components, ensuring optimal performance and longevity.

Full Flow Oil Filter

In the full flow oil filter system, the O-Ring Seal is positioned to create a tight seal between the filter and the engine block or filter housing. This seal prevents oil leaks and ensures that the oil flows through the filter media without bypassing, which is essential for effective filtration and contaminant removal.

Lubricating Oil System

Within the lubricating oil system, the O-Ring Seal is utilized in the connections between the oil pump, galleries, and passages. It ensures that the lubricating oil is delivered under pressure to all moving parts without any loss, thereby maintaining consistent lubrication and reducing wear.

Hydraulic Kit

In hydraulic kits, the O-Ring Seal is critical for maintaining pressure integrity. It is used in the connections between hydraulic components such as pumps, valves, and actuators. The seal prevents hydraulic fluid leaks, ensuring that the system operates with the required pressure and efficiency.

Lubricating Oil Filter

For the lubricating oil filter, the O-Ring Seal is employed at the interface between the filter element and the filter housing. This ensures that the oil passes through the filter media and not around it, enhancing the filtration process and protecting engine components from abrasive particles.

Lubricating Oil Filter Head

In the lubricating oil filter head, the O-Ring Seal is used to secure the filter element in place. It creates a barrier that prevents oil from leaking out while allowing it to flow through the filter, thus maintaining the cleanliness of the lubricating oil.

Lubricating Oil Filter Kit

Within a lubricating oil filter kit, the O-Ring Seal is a common component in various connections and interfaces. It ensures that all parts of the kit—including the filter housing, bypass valve, and relief valve—are sealed properly. This integrity is vital for the kit’s overall performance in filtering and maintaining the quality of the lubricating oil.
