1202 Series Bypass Filter Element: Applications, Benefits, and Buying Guide

Clean hydraulic and lubricating oil plays an important role in maintaining reliable industrial equipment. The 1202 bypass filter element from Harvard Filtration is designed for applications involving hydraulic oil, engine oil, cutting oil, diesel fuel, and other compatible low-viscosity petroleum or synthetic fluids. It provides fine filtration and can remove contaminants as small as 1 micron, helping maintenance teams manage particulate and water contamination.

What Is the 1202 Series Filter Element?

The 1202 Series Element is a bypass filtration element designed for oil-cleaning applications. It removes particles and water without depleting oil additives, making it suitable for facilities that want to improve fluid cleanliness while supporting oil-management and preventive-maintenance programs. Harvard Filtration specifies a Beta3 rating of 250 and a maximum operating pressure of 125 PSI.

Each compatible housing requires two 1202 filter elements, and the product is designed around housing configurations with a 56-quart/53-liter makeup-fluid requirement per filter set.

Where Can the 1202 Bypass Filter Element Be Used?

The 1202 Series can support a variety of industrial oil-filtration applications across the USA, including:

• Hydraulic equipment and machinery

• Industrial lubrication systems

• Engine oil filtration

• Cutting-oil applications

• Diesel fuel filtration

• Manufacturing equipment

• Construction and heavy-duty machinery

Its recommended fluid viscosities include Diesel, ISO 10, 15, 22, and 32, and SAE 5W and 10W. The specified ideal sump range extends from 23 to 1,000 gallons, depending on the application and housing configuration.

Key Benefits of the 1202 Series

A properly selected 1202 filter element can help industrial maintenance teams:

Control contamination: Fine filtration helps capture small particulate contaminants.

Support oil cleanliness: Cleaner oil can help protect pumps, valves, and other hydraulic components.

Remove water and particles: The element is designed to address both water and particulate contamination.

Support preventive maintenance: Offline or bypass filtration can complement existing hydraulic filtration practices.

Improve filtration flexibility: The 1202 Series can be used across specified hydraulic, lubrication, and diesel applications.

1202 Filter Element Maintenance

Filter performance depends on oil viscosity, operating temperature, contamination levels, and flow requirements. Harvard Filtration recommends that most applications change elements between 500 and 1,000 operating hours, while also monitoring changes in flow and pressure. An element should ideally be changed when flow reaches approximately half of its starting level or pressure reaches twice its starting level.
