Hot sale HITACHI 120-5 ENGINE OIL FILTER HEAD | Tonkee®

The engine oil filter head for the Hitachi 120-5 is typically constructed from high-quality materials, often featuring robust cast iron or aluminum alloy.

These materials are chosen for their durability and resistance to corrosion, which is essential for a component exposed to engine oil.

Design and Functionality:

The filter head is a critical part of the engine's lubrication system. Its primary function is to hold and secure the engine oil filter element in place and provide a housing for the filter. The design of the filter head includes multiple ports and connections for the flow of oil. It is typically mounted to the engine block or another suitable location.

Oil Inlet and Outlet Ports:

One of the most critical specifications of the oil filter head is the size and configuration of the oil inlet and outlet ports. These ports determine the flow rate and direction of the engine oil as it passes through the filter. The size and design of these ports must be compatible with the engine's oil circulation requirements.

Thread Size and Type:

The filter head will have threaded connections for attaching the oil filter element and connecting to the engine's oil lines.

The thread size and type must match those of the oil filter and the engine to ensure a secure and leak-free connection.

Pressure Relief Valve:

Many engine oil filter heads incorporate a pressure relief valve. This valve is designed to open if the oil pressure within the system becomes too high, preventing damage to the filter element and other components. The specifications of this valve, including its opening pressure, are crucial for maintaining the engine's proper oil pressure.

Mounting Compatibility:

The filter head must be designed to be compatible with the mounting points on the engine block or other installation locations. This ensures a secure and stable attachment, preventing vibrations or other forces from causing damage or leaks.

Filtration Efficiency:

While the primary function of the filter head is to house the filter element, its design can also impact filtration efficiency. The filter head must support the filter element in a way that ensures a tight seal and prevents bypass of unfiltered oil. Specifications related to filtration efficiency are vital for maintaining the cleanliness of the engine oil.

Maintenance and Serviceability:

Ease of maintenance is another important consideration for the filter head. It should be designed for easy access during oil changes and filter replacements. This often involves the inclusion of a built-in wrench or other features to facilitate removal and installation.
