Pall HC7500SDN4H Replacement Filter Element - Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-744509-L4-6MB | Ships same day from Detroit, MI | OEM-equivalent performance
If you need a replacement for the Pall HC7500SDN4H, you're maintaining a hydraulic system that calls for a 6-micron return line element with standard Buna-N sealing. The Hydrafil BF-PAL-744509-L4-6MB is a direct drop-in replacement built to the same dimensional and performance standards using microglass fiber media manufactured and sourced in the USA.
Dimensional Specifications
The BF-PAL-744509-L4-6MB matches the HC7500SDN4H in all critical dimensions, ensuring proper fitment in your existing filter housing with no modification required.
| Specification | Value |
|---|---|
| Outer Diameter (Top) | 5.06 in |
| Outer Diameter (Bottom) | 5.06 in |
| Element Length | 6.9 in |
| Thread Size | 1.5-16 UNF |
| Collapse Rating | 100 psid |
Media & Construction
Filter media and materials of construction directly affect element life, fluid compatibility, and filtration efficiency. The specifications below match the OEM Pall element:
- Filtration Media: Microglass Fiber - higher dirt-holding capacity and lower pressure drop than cellulose alternatives
- Seal Material: Buna-N (Nitrile) - compatible with petroleum-based hydraulic fluids, standard mineral oils, and most HFA/HFB fire-resistant fluids
- End Caps: Corrosion Resistant Steel - prevents bypass during cold-start high-viscosity conditions
- Center Tube: Corrosion Resistant Steel - maintains structural integrity at system pressure
Filtration Performance Rating
The BF-PAL-744509-L4-6MB achieves 6-micron absolute filtration at Beta 1000 (Bx[c=6?m] = 1000), removing 99.9% of particles at 6 microns and larger in a single pass. This rating is consistent with the original Pall HC7500SDN4H specification.
The multi-pass Beta rating (Bx[6?m] = 200) reflects 99.5% efficiency under ISO 16889 multi-pass test conditions - the industry standard for hydraulic filter element performance.
Why this matters: 6-micron absolute filtration targets the particle size range most damaging to servo valves, proportional valves, and high-pressure piston pumps. Maintaining this rating at every replacement interval protects your highest-value components.
ISO Standards Compliance
Hydrafil filter elements are tested to the same ISO standards required of OEM elements. The BF-PAL-744509-L4-6MB is tested in compliance with:
| ISO Standard | What It Tests |
|---|---|
| ISO 2941 | Collapse & burst resistance |
| ISO 2942 | Fabrication integrity & bypass valve function |
| ISO 2943 | Material compatibility with hydraulic fluids |
| ISO 3724 | Flow fatigue characteristics |
| ISO 3968 | Pressure drop vs.?flow rate characteristics |
| ISO 16889 | Multi-pass performance (Beta ratio methodology) |
About the Pall HC7500SDN4H
The Pall HC7500 series is a medium-pressure return line filter element used across a broad range of industrial and mobile hydraulic systems. The SDN4H designation identifies a 6.9-inch element in the standard single-pass configuration with Buna-N (Nitrile) sealing - the correct choice for systems running petroleum-based hydraulic fluid at standard operating temperatures. Common applications include industrial power units, injection molding machines, press circuits, CNC machine tools, and mobile hydraulic equipment.
