Pall HC7500SCT8H Replacement Filter Element — Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-617018-L8-25MB | Ships same day from Detroit, MI | OEM-equivalent performance
The HC7500SCT8H is the 25-micron, Buna-N, long-body (10.9 in) element — the highest-capacity coarse-rated element in the HC7500 series and the workhorse spec for high-flow return lines on large petroleum-based industrial hydraulic systems. The combination of a 25µm rating with the extended L8 body maximizes dirt-holding capacity and minimizes pressure drop under high flow, making it the filter of choice for large press hydraulics, bulk material handling, steel mill auxiliary circuits, and any high-volume power unit where long service intervals between element changes are non-negotiable.
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 — higher dirt-holding capacity than cellulose at the 25-micron rating, delivering long service intervals in high-flow, coarse-contamination hydraulic circuits
- 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 25 microns, this element is tuned for bulk contamination control — capturing coarse wear debris, pipe scale, weld slag from new-build systems, and the larger ingressed particles that pose immediate risk of catastrophic pump damage or valve spool seizure. The coarse rating also minimizes clean-element pressure drop, which matters on cold-start and high-flow systems where finer elements would saturate prematurely.
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 25µm Buna-N element in the L8 long body is the default long-life return-line filter for high-flow industrial power units — large hydraulic presses, heavy mobile equipment shop reservoirs, and continuous industrial off-line recirculating systems. The coarse rating keeps pressure drop manageable even at peak flow, while the extended L8 capacity delivers the longest practical service interval before the element saturates and goes into bypass.
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 HC7500SCT8H
The HC7500SCT8H is specified into the largest petroleum-oil-based industrial hydraulic systems — stamping and forging presses, steel mill auxiliary hydraulics, bulk crushing and screening plants, and large off-line recirculating filter carts. The 25µm rating protects standard pumps and valves from the coarse wear debris that dominates ingression in these high-flow, high-volume systems, and the L8 body delivers the dirt-holding capacity needed to keep service intervals aligned with the host equipment’s scheduled maintenance cycles. Buna-N seals are adequate for the mineral-oil hydraulic fluids used almost universally in this service class.
