Use cases & applications
High-Pressure Hydraulic Circuits
In systems operating under constant high pressure, the 25 bar collapse rating ensures the element remains intact and effective. It prevents particle ingression that could score valves and cylinders, extending component life.
Contamination-Sensitive Applications
For machinery where even microscopic debris causes malfunction, the 5 µm inorganic microfibre media captures fine silt and wear particles. This maintains fluid ISO cleanliness levels, reducing unplanned downtime on precision equipment.
Continuous-Duty Operations
Fleets running around the clock benefit from the long service life of this filter. It holds significant contaminant capacity, meaning fewer change-outs, less labour, and consistent protection over extended intervals.
Dusty or Dirty Environments
On mobile equipment exposed to airborne dust, the filter prevents external contaminants from cycling through the hydraulic loop. It safeguards pumps and motors, keeping field operations productive and repair bills low.
Frequently asked questions
How do I know this filter will fit my machine?
This filter cross-references to numerous branded part numbers, covering equipment from Hydac and other makers. Confirm that your existing element shares the same dimensions (body height 315 mm, total height 321 mm, largest OD 94 mm) and flow direction (out-in). These details ensure a correct fit.
What is the filtration rating and media type?
This element is rated at 5 µm absolute using inorganic microfibre media. The media provides high dirt-holding capacity and consistent particle removal, critical for maintaining hydraulic system cleanliness and preventing abrasive wear.
Does this filter have the correct thread and dimensions for my housing?
The filter features a largest inner diameter of 48.4 mm and smallest inner diameter of 30 mm, designed to match common hydraulic filter heads. Always compare these measurements and the outer diameter (94 mm) with your current element to ensure proper seating and seal integrity.
Is this a genuine Hydac or Parker filter?
No, this filter is an aftermarket filter. It is built to match the form, fit, and filtration performance of the original brands it replaces, offering a cost-effective alternative without compromising on protection.
How often should this hydraulic filter be replaced?
Replacement intervals depend on operating conditions, duty cycle, and fluid cleanliness targets. Install the new element when the system indicates high differential pressure or during scheduled maintenance. Regular monitoring of condition indicators will optimise element life.
What delivery options and guarantees do you provide?
We ship worldwide with tracking. Your purchase is covered by a 30-day money-back guarantee for peace of mind. Additionally, if you find a lower price for the same filter elsewhere, we offer a price-beat guarantee.
