Pall HC7500SDS4H Replacement Filter Element — Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-804616-L4-12MB | Ships same day from Detroit, MI | OEM-equivalent performance
The HC7500SDS4H fills the intermediate filtration band in the HC7500 series at 12µm — coarser than the 6µm SDN and 3µm SDP servo-grade elements, but significantly finer than the 25µm SDT general-purpose variant. With Buna-N (Nitrile) seals in the compact 6.9 in L4 body, the Hydrafil BF-PAL-804616-L4-12MB is the right replacement for return-line and medium-pressure circuits on standard mineral oil where the application requires better cleanliness than general industrial hydraulics but doesn’t carry components sensitive enough to justify sub-6-micron elements. It’s commonly specified for gear pump protection, proportional valve pilot circuits, and systems targeting ISO cleanliness codes in the 17/15/12 range.
Dimensional Specifications
A consistent dimensional match with the OEM element ensures proper seating against the filter head and correct engagement with the bypass valve indicator — always verify length and thread before installation.
| 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
Microglass fiber media at 12µm offers the consistency and service life advantages of synthetic media over cellulose across the intermediate filtration range.
- Filtration Media: Microglass Fiber Media — at 12µm, microglass delivers a more precise and consistent pore structure than cellulose alternatives, translating to stable Beta ratios across the element’s service life rather than the performance drift that occurs as cellulose fibers swell and shift; the correct choice for circuits where repeatable cleanliness is more important than lowest cost-per-element
- Seal Material: Buna-N (Nitrile) — compatible with petroleum-based hydraulic oils and water-glycol fluids in the standard operating range to approximately 200 °F; the appropriate seal for conventional mineral oil industrial hydraulic systems
- 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
At 12µm, this element targets particle sizes that cause accelerated wear in gear pumps, vane pumps, and moderate-clearance proportional valves — components that don’t require the sub-5-micron cleanliness of servo systems but are still sensitive to particles in the 10–25µm range. Beta Bx = 200 and Bx[c] = 1000 at the 12µm rating delivers consistent multi-pass efficiency appropriate for achieving and maintaining ISO Class 17/15/12 to 16/14/11 in medium-duty industrial hydraulic circuits.
The 12µm Buna-N L4 element is the practical choice for gear pump protection, proportional valve pilot supply circuits, and general industrial return lines on mineral oil where engineers need demonstrably better-than-25µm cleanliness without the cost or delta-P of a servo-grade fine element.
ISO Standards Compliance

About the Pall HC7500SDS4H
The HC7500SDS4H is the 12µm Buna-N short-body element in Pall’s HC7500 series, occupying the middle ground between general-purpose 25µm return-line filtration and precision servo-grade elements. It is found in a wide range of industrial hydraulic machinery — injection molding auxiliaries, mobile equipment return lines, machine tool coolant-side hydraulics, and any application where the system designer determined that 25µm was insufficient but the cost and pressure drop of 3 or 6µm filtration could not be justified. The compact 6.9 in L4 body makes it suitable for installations with limited housing depth, fitting the same HC7500-series filter heads used across the broader product family.
