Pall HC7500SUT8Z Replacement Filter Element - Cross-Reference & Specifications
Pall HC7500SUT8Z Replacement Filter Element - Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-449577-L8-25MV | Ships same day from Detroit, MI | OEM-equivalent performance
The Pall HC7500SUT8Z combines two demanding requirements into a single element: the high flow capacity of the long-body (10.9 in) format and the chemical resistance of Viton (Fluorocarbon) seals needed for phosphate ester or synthetic hydraulic fluid systems. This configuration is specified for large industrial systems - steel processing lines, die casting operations, and aerospace ground support equipment - where the fluid chemistry rules out Buna-N seals and the system flow rate rules out the shorter L4 element. It's among the more specialized HC7500 variants, and finding a reliable aftermarket source is what brings most engineers here.
Dimensional Specifications
The BF-PAL-449577-L8-25MV matches the HC7500SUT8Z in all critical dimensions for a direct drop-in installation in your existing filter housing.
| Specification | Value |
|---|---|
| Outer Diameter (Top) | 5.06 in |
| Outer Diameter (Bottom) | 5.06 in |
| Element Length | 10.9 in |
| Thread Size | 1.5-16 UNF |
| Collapse Rating | 100 psid |
Media & Construction
Every material specification on this element is chosen for high-flow synthetic fluid service, matching the OEM Pall configuration:
- Filtration Media: Microglass Fiber - the extended media area of the L8 body maintains low pressure drop at high flow rates, reducing energy consumption and extending element life versus cellulose alternatives
- Seal Material: Viton (Fluorocarbon) - resists phosphate ester fluids, polyol ester synthetics, and operating temperatures up to 225?F; required in systems where Buna-N seals would swell or degrade with the working fluid
- End Caps: Corrosion Resistant Steel - reliable seal integrity under the pressure cycling typical of large multi-actuator systems
- Center Tube: Corrosion Resistant Steel - structural support against collapse at rated 100 psid differential pressure
Filtration Performance Rating
The BF-PAL-449577-L8-25MV achieves Bx[c=25?m] = 1000 (99.9% single-pass efficiency at 25 microns) and a multi-pass Beta value of Bx[25?m] = 200 per ISO 16889 - matching the OEM HC7500SUT8Z specification. The 10.9-inch body maintains these ratings across the higher flow rates demanded by large hydraulic circuits running on synthetic fluids.
This is the correct element when you need both Viton seals and high flow capacity - specifying an L4 element with Viton seals in a high-flow synthetic fluid system will result in excessive differential pressure and shortened service intervals. The SUT8Z exists precisely for this combination of requirements.
ISO Standards Compliance
Hydrafil elements are manufactured and tested to the same ISO standards Pall applies to OEM elements. The BF-PAL-449577-L8-25MV 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 HC7500SUT8Z
The HC7500SUT8Z is a specialty configuration within Pall's HC7500 series, selected specifically when both high flow capacity and synthetic fluid compatibility are required. It is commonly found in large-tonnage die casting machines and steel mill hydraulics using fire-resistant phosphate ester fluids, as well as in aerospace and defense ground support equipment operating on polyol ester synthetic fluids. The L8 long-body format is specified when system flow rates exceed the capacity of the standard L4 element, while the Viton seal ensures long-term compatibility with the working fluid chemistry.
