Pall HC7500SCT4H Replacement Filter Element — Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-903183-L4-25MB | Ships same day from Detroit, MI | OEM-equivalent performance
The HC7500SCT4H is a 25-micron, Buna-N-sealed, short-body (6.9 in) element built for the cost-conscious general industrial and mobile hydraulic maintenance programs where the job is first-stage contamination control, not precision cleanliness. At 25µm the element captures the bulk contaminants — coarse wear debris, weld slag, pipe scale, seal fragments — that protect pumps and directional valves from catastrophic failure while minimizing pressure drop and extending service life between changeouts. The compact L4 form factor fits tank-top and inline housings common across construction, agricultural, and light industrial equipment.
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 | 6.9 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 L4 compact body is the workhorse specification for mobile equipment return lines, suction-strainer replacements on low-pressure charge circuits, and general industrial off-line polishing where the operator tolerance is set to standard ISO 20/18/15 cleanliness rather than servo-grade targets. This is the element to reach for when the priority is low pressure drop, long service intervals, and lowest cost per hour of machine runtime.
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 HC7500SCT4H
The HC7500SCT4H sees heavy use in construction and agricultural hydraulics — excavators, loaders, harvest equipment — as well as general industrial power units, conveyor drives, and bulk-handling hydraulics. The 25µm rating is tuned to protect standard gear and vane pumps without imposing the pressure-drop penalty of finer media, and Buna-N seals cover the petroleum-based fluids that dominate these markets. The L4 short body fits space-constrained housings found on mobile equipment and compact industrial power units where element envelope is a design constraint.
