Pall HC7500SCS8H Replacement Filter Element — Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-558955-L8-12MB | Ships same day from Detroit, MI | OEM-equivalent performance
The HC7500SCS8H is a 12-micron, Buna-N-sealed, long-body (10.9 in) element engineered for higher-flow return-line and off-line filtration in industrial hydraulic systems that run petroleum-based mineral oil. The extended L8 body roughly doubles the effective media surface area versus the compact L4, allowing heavy-duty power units, large press circuits, and high-capacity mobile hydraulics to capture the mid-range 12µm wear particles that drive pump degradation without forcing short service intervals. This is the workhorse long-body spec for industrial return lines where uptime between changeouts matters more than servo-grade cleanliness.
Dimensional Specifications
An exact dimensional match is required for proper housing seating, bypass valve operation, and full-perimeter seal engagement.
| 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
Material selection in this element balances particle capture efficiency with dirt-holding capacity for the fluid chemistry and operating conditions where this variant is deployed.
- Filtration Media: Microglass Fiber Media — significantly higher particle capture efficiency than cellulose at the 12-micron rating, with the dirt-holding capacity to support long service intervals on mid-range contamination loads
- Seal Material: Buna-N (Nitrile) — the standard seal material for petroleum-based mineral oil, water-glycol, and water-oil emulsion hydraulic fluids; compatible with virtually every general industrial hydraulic fluid specification up to roughly 200°F continuous service
- End Caps: Corrosion Resistant Steel — corrosion resistant for long service life
- Center Tube: Corrosion Resistant Steel — maintains structural integrity under pressure cycling and differential pressure spikes during cold-start flow surges
Filtration Performance Rating
At 12 microns, this element targets the mid-range contamination particles — abrasive wear debris, atmospheric dust ingressed through breather vents, and pump-generated metallic fines — that drive accelerated pump efficiency loss and control valve spool erosion in standard industrial hydraulic circuits.
The filtration rating is verified to Bx = 200 (≥99.5% capture at the rated micron size) and Bx[c] = 1000 (≥99.9% capture) per ISO 16889 multi-pass testing — the methodology that measures real-world efficiency under sustained contaminant loading, not the single-pass nominal ratings that older filter specifications sometimes cite.
A 12µm Buna-N element in the L8 long body is the preferred specification for high-flow return lines, case drains, and off-line recirculating filtration in industrial power units where extended media capacity reduces annual changeout frequency. The extra surface area is especially valuable in dusty plant environments — foundries, woodworking mills, and bulk material handling — where contamination ingression rates are elevated and L4 elements would load up prematurely.
ISO Standards Compliance
This element is manufactured and tested to the hydraulic filter standards that govern structural integrity, fabrication quality, fluid compatibility, and filtration performance:
| 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 HC7500SCS8H
The HC7500SCS8H is specified into large industrial hydraulic systems across stamping presses, injection molding machinery, steel mill auxiliaries, and high-flow mobile equipment power units. The 12µm rating protects standard pumps and directional valves without the cold-start penalty of 3µm or 6µm elements, while the 10.9 in body provides the dirt-holding capacity needed to maintain reasonable service intervals in systems with higher fluid volumes and higher ingression rates. Buna-N seals cover the standard mineral oil and water-glycol fluid ranges that predominate in general industrial hydraulics.
