Stauff NL250F03B, direct aftermarket replacement. This filter is an aftermarket hydraulic filter element built as a direct replacement for OEM parts from Hydac and other leading brands. It utilises a 5-micron inorganic microfibre media to deliver fine particle removal in high-pressure hydraulic circuits. The out-to-in flow path ensures consistent filtration, and the robust design withstands element collapse pressures up to 210 bar. This filter element offers a cost-effective alternative without sacrificing fit or function, making it a smart choice for maintenance teams managing multiple equipment brands. With key dimensions of 250 mm total height, 40.5 mm inner diameter, and 78 mm outer diameter, it matches factory specifications for straightforward installation.

Use cases & applications
High-Pressure Circuit Protection
When hydraulic systems operate under extreme conditions, component protection is critical. With an element collapse pressure of 210 bar, this filter maintains integrity even during pressure spikes, preventing bypass and safeguarding pumps and valves.
Fine Contamination Control
In applications where fluid cleanliness is paramount, the 5-micron inorganic microfibre media captures silt and wear particles that larger filters miss. This extends the life of servo valves and precision actuators in sensitive machinery.
Streamlined Maintenance Scheduling
Because this filter cross-references multiple brand part numbers, it reduces inventory complexity. Maintenance teams can hold a single part for various machines, simplifying reordering and minimising downtime during routine service intervals.
Operational Reliability in Dirty Environments
Whether in mining, construction, or industrial manufacturing, airborne dust and process contaminants threaten hydraulic systems. The efficient media loading capacity of this filter ensures long service life and stable pressure differentials, keeping equipment running reliably between changes.
Frequently asked questions
Is this filter a genuine Hydac filter?
No, it is an aftermarket replacement built to the original dimensions and ratings of Hydac and other brands. It provides equivalent fit and filtration performance at a more competitive price.
What is the filtration rating of this element?
The media is inorganic microfibre rated at 5 µm, delivering efficient particle removal for hydraulic fluids.
What are the critical dimensions to ensure a correct fit?
Total height is 250 mm, largest inner diameter 40.5 mm, and largest outer diameter 78 mm. These match the OEM design for Hydac-compatible housings. Always verify against your housing specifications before ordering.
How does this aftermarket filter compare to the branded version?
It is manufactured to equivalent performance standards, using the same filtration media type and collapse pressure rating. The primary difference is that it does not carry the OEM brand name, which allows us to offer it at a lower cost.
How do I install this hydraulic filter element?
Installation is straightforward. Depressurise the hydraulic system, remove the old element, and insert this filter following the equipment manufacturer's instructions. Always replace seals and lubricate as specified.
