Pall HC7500SUT4Z Replacement Filter Element - Cross-Reference & Specifications
Pall HC7500SUT4Z Replacement Filter Element - Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-116563-L4-25MV | Ships same day from Detroit, MI | OEM-equivalent performance
The Pall HC7500SUT4Z is a compact 25-micron return line element specified for systems running phosphate ester fluids, synthetic hydraulic fluids, or other chemically aggressive media - the Viton (Fluorocarbon) seal is what sets this configuration apart from its Buna-N counterpart. At 6.9 inches in length, it's engineered for space-constrained housings where both chemical compatibility and a 25-micron general-duty rating are required, making it a common choice in fire-resistant fluid systems in steel mills, die casting operations, and high-temperature industrial environments.
Dimensional Specifications
The BF-PAL-116563-L4-25MV matches the HC7500SUT4Z in all critical dimensions, ensuring direct installation in your existing housing without modification.
| 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
The construction of this element is engineered specifically for compatibility with synthetic and specialty hydraulic fluids, while delivering consistent 25-micron filtration performance:
- Filtration Media: Microglass Fiber - provides lower pressure drop and higher dirt-holding capacity than cellulose for extended service intervals
- Seal Material: Viton (Fluorocarbon) - resistant to phosphate ester fluids, synthetic esters, and elevated operating temperatures up to 225?F, where Buna-N seals would degrade
- End Caps: Corrosion Resistant Steel - prevents element bypass during cold-start high-viscosity surges
- Center Tube: Corrosion Resistant Steel - maintains structural integrity through pressure cycling at 100 psid collapse rating
Filtration Performance Rating
At 25 microns absolute, the BF-PAL-116563-L4-25MV achieves Bx[c=25?m] = 1000, meaning it captures 99.9% of particles 25 microns and larger in a single pass. The multi-pass Beta value of Bx[25?m] = 200 reflects 99.5% efficiency under sustained multi-pass operating conditions per ISO 16889.
For phosphate ester and synthetic fluid systems, the 25?m Viton configuration is the correct choice - running a Buna-N seal in these fluids causes swelling and seal degradation, resulting in bypass leakage and contaminated fluid reaching downstream components.
ISO Standards Compliance
Hydrafil elements are manufactured and tested to the same ISO standards Pall applies to OEM elements. The BF-PAL-116563-L4-25MV 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 HC7500SUT4Z
The HC7500SUT4Z belongs to Pall's HC7500 medium-pressure hydraulic filtration series and is specifically selected when a facility's hydraulic system operates on synthetic or fire-resistant fluids rather than mineral oil. Typical applications include steel mill roll stand hydraulics, die casting machine circuits, and other industrial systems where fluid fire resistance is required by safety code. The compact L4 (6.9 in) body suits standard-sized housing installations common in machine tool and press hydraulic power units using these specialty fluids.
