Pall HC7500SCS4Z Replacement Filter Element — Cross-Reference & Specifications
Pall HC7500SCS4Z Replacement Filter Element — Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-195817-L4-12MV | Ships same day from Detroit, MI | OEM-equivalent performance
The HC7500SCS4Z addresses a specific and common maintenance challenge: general-purpose 12-micron filtration in compact housings where the system fluid requires Viton-compatible seals. Whether the hydraulic circuit runs phosphate ester, polyol ester synthetic, or a specialty fluid that would degrade standard nitrile seals, this element delivers mid-range particle capture without sacrificing seal integrity in a space-constrained L4 short-body installation. It’s frequently specified as the return-line or pre-filter element in industrial fire-resistant fluid systems — die casting, forging, heat treating, and similar applications where process hazard ratings mandate non-petroleum hydraulic fluids in compact power unit formats.
Dimensional Specifications
Housing compatibility depends on exact dimensional match — the 5.06 in OD and 1.5-16 thread must correspond precisely to the Pall HC7500 housing to ensure full seating and bypass valve contact.
| Specification | Value |
|---|---|
| Outer Diameter (Top) | 5.06 in |
| Outer Diameter (Bottom) | 5.06 in |
| Element Length | 6.9 in |
| Thread Size | 1.5 - 16 |
| Collapse Rating | 100 psid |
Media & Construction
Material selection is optimized for reliable performance in synthetic and fire-resistant hydraulic fluid environments within a compact element footprint.
- Filtration Media: Microglass Fiber Media — consistent 12µm efficiency with greater dirt-holding capacity than cellulose equivalents, maintaining lower differential pressure over longer service intervals even in contamination-prone industrial environments
- Seal Material: Viton (Fluorocarbon) — essential for phosphate ester (Skydrol, Fyrquel), polyol ester, and other synthetic hydraulic fluids that attack nitrile compounds; maintains dimensional stability at elevated fluid temperatures up to approximately 400°F (204°C)
- End Caps: Corrosion Resistant Steel — corrosion resistant for long service life across the chemically diverse fluids encountered in fire-resistant hydraulic systems
- Center Tube: Corrosion Resistant Steel — maintains structural integrity under pressure cycling and bypass valve actuation loads
Filtration Performance Rating
At 12 microns, this element captures the bulk of abrasive mid-range contamination — ingressed environmental particulate, pump wear debris, and system-generated contamination — that accelerates component wear in hydraulic systems using synthetic or fire-resistant base fluids.
The HC7500SCS4Z is the correct element when the housing is an L4 short body, the system uses a non-petroleum hydraulic fluid, and the maintenance specification calls for 12µm return-line or pre-filter protection. Using a Buna-N seal in a phosphate ester system will result in seal swelling, housing leakage, and element bypass — Viton is not optional in these circuits.
ISO Standards Compliance
This element is manufactured and tested to the following ISO hydraulic filter standards:
| 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 HC7500SCS4Z
The HC7500SCS4Z is the maintenance element of choice in fire-resistant fluid hydraulic systems where the housing accepts a short-body element and mid-range filtration is specified — die casting machines, induction heating press circuits, forging press hydraulics, and industrial power units operating in environments where local fire codes require non-petroleum hydraulic fluid. The Viton seal removes the risk of fluid-seal incompatibility that makes standard Buna-N elements unsuitable in these circuits, while the 12µm microglass media delivers reliable contamination control across extended drain intervals typical of synthetic hydraulic fluid systems.
