Pall HC7500SCN8Z Replacement Filter Element — Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-815849-L8-6MV | Ships same day from Detroit, MI | OEM-equivalent performance
The HC7500SCN8Z combines three demanding specifications in a single element: 6-micron absolute filtration, Viton (Fluorocarbon) seals, and the long L8 body (10.9 in) for high-flow systems — making it the element of choice for large hydraulic power units running fire-resistant phosphate ester or synthetic ester fluids, where flow rates are high, servo valve cleanliness targets are strict, and seal chemical compatibility is a hard requirement. This configuration appears in steel mill hydraulics, aluminum die-casting machines, and large offshore or energy-sector hydraulic systems running Fyrquel or Skydrol-type fluids at elevated temperatures and high flow rates.
Dimensional Specifications
The L8 body (10.9 in) provides maximum filter media area within the HC7500 50-AT series housing — verify housing length clearance before ordering, as both L4 and L8 housings share the same 5.06 in OD and 1.5-16 thread interface.
| Specification | Value |
|---|---|
| Outer Diameter (Top) | 5.06 in |
| Outer Diameter (Bottom) | 5.06 in |
| Element Length | 10.9 in |
| Thread Size | 1.5 - 16 |
| Collapse Rating | 100 psid |
Media & Construction
The SCN8Z’s combination of microglass media and Viton seals addresses the dual challenge of ultra-fine contamination control and aggressive fluid compatibility in high-throughput industrial systems.
- Filtration Media: Microglass Fiber Media — the L8 body provides expanded media area for lower differential pressure at high flow rates while maintaining absolute 6µm particle capture; resists media migration under thermal cycling and high-flow surge conditions
- Seal Material: Viton (Fluorocarbon) — engineered for phosphate ester fire-resistant fluids, synthetic esters, polyol esters, and high-temperature mineral oil applications; temperature resistant to +400°F, resisting swell and degradation where Buna-N seals would fail
- End Caps: Corrosion Resistant Steel — corrosion resistant for long service life
- Center Tube: Corrosion Resistant Steel — maintains structural integrity under pressure cycling
Filtration Performance Rating
Six-micron filtration in the L8 body maintains ISO 4406 Class 15/13/10 fluid cleanliness across high system flow rates without the pressure drop penalty that would trigger the bypass valve in a smaller element. This is the critical spec for servo valve circuits in large HPUs where a single element must protect multiple downstream valves.
6µm Viton in the high-flow L8 body: engineered for large phosphate ester fluid systems in steel mills, die-casting plants, and energy-sector equipment where servo valve protection must be maintained at high flow rates with aggressive, high-temperature fluids.
| Beta Rating | Value |
|---|---|
| Bx | 200 |
| Bx[c] | 1000 |
ISO Standards Compliance
Comprehensive ISO testing validates this element for the demanding environments where the SCN8Z configuration is typically deployed.

| 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 HC7500SCN8Z
The HC7500SCN8Z is specified for the most demanding hydraulic filtration scenarios: large centralized power units running phosphate ester or synthetic ester fire-resistant fluids, where system flow rates require the high-capacity L8 element body, servo or proportional valve circuits demand 6µm absolute filtration, and Viton seals are mandated by the fluid specification. Typical applications include primary rolling mill drives, large die-casting injection systems, and offshore hydraulic power packs.
