Product Information

Full details

The MANN-FILTER HD 825/2 hydraulic oil filter is designed for heavy-duty industrial and machinery maintenance professionals who require original equipment quality for high-pressure systems. Its primary benefit is the superior separation of microscopic impurities from hydraulic fluids, which significantly extends the operational lifespan of critical system components. A key caveat to note is that this is a filter insert, meaning it requires existing housing compatibility and careful handling during installation to maintain its seal integrity.

Extended Product Information

FAQs

What are the exact dimensions of the HD 825/2?

The filter is 117 mm in height, with an outer diameter of 78 mm and an inner diameter of 42 mm.

Is this a direct replacement for my OEM filter?

Yes, it is built to original equipment quality standards, designed to match the fit and filtration performance of standard factory-installed units.

How often should I change this filter?

Always follow the maintenance interval specified by your machine's manufacturer, as hydraulic load and operating environment heavily influence service life.

Can this filter be cleaned and reused?

No, this is a disposable filter insert. Attempting to clean the media can damage its structure and lead to catastrophic hydraulic failure.

Does this package include a new gasket?

The filter insert does not typically come with secondary housing gaskets; you must use the seals provided with your specific filter housing.

What is the primary function of this filter?

Its primary function is to remove fine contaminants from hydraulic oil, ensuring the long-term reliability and integrity of hydraulic pumps and valves.

Troubleshooting

System pressure remains high after filter change

Verify the filter is seated correctly in the housing and check that the bypass valve is not stuck.

Evidence of fluid leakage around the filter housing

Check the condition of the housing seals or O-rings; ensure the housing cover is tightened to the manufacturer's specified torque.

Pros and Cons

Pros

  • Superior protection against fine particle contamination
  • Reliable performance under high-pressure conditions
  • Matches strict OEM quality standards
  • Helps extend the interval between major system repairs

Cons

  • Requires careful alignment during installation
  • Compatibility is limited to specific housing types
  • Does not include housing components or O-rings

Setup, Compatibility & Care

To ensure proper function, first verify that your hydraulic housing dimensions match the HD 825/2 specifications: 117 mm height, 78 mm outer diameter, and 42 mm inner diameter. When installing, always depressurize the hydraulic system completely to avoid fluid injection injuries. Ensure the sealing surfaces are clean and free of debris before inserting the filter. Because this is a high-precision component, avoid touching the filter media with oily or dirty hands. After installation, bleed the air from the hydraulic circuit according to your machine's service manual to ensure optimal performance from the first startup.
