Pall HC7500SCN8H Replacement Filter Element — Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-126269-L8-6MB | Ships same day from Detroit, MI | OEM-equivalent performance
The HC7500SCN8H is the long-body (L8, 10.9 in) version of Pall’s 6-micron Buna-N element in the HC7500 50-AT spin-on series — specified for high-flow precision hydraulic systems where greater dirt-holding capacity and extended service intervals are required alongside servo-valve-grade filtration. The longer element body provides substantially higher flow capacity than the L4 variant at equivalent pressure drop, making this configuration the right fit for large industrial presses, multi-actuator machine tool systems, and centralized hydraulic power units running multiple servo or proportional valve circuits simultaneously.
Dimensional Specifications
The L8 body requires a housing sized for the 10.9 in element length — confirm housing compatibility before ordering, as the HC7500 series offers both L4 and L8 housings with identical thread and OD specifications.
| 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
The L8 microglass element offers the same absolute 6µm rating as the L4 but with a significantly larger filtration surface area for demanding high-flow applications.
- Filtration Media: Microglass Fiber Media — larger surface area in L8 body extends service life and reduces bypass risk in high-flow, high-contamination environments; absolute 6µm rating protects precision servo valve clearances
- Seal Material: Buna-N (Nitrile) — reliable elastomeric seal for mineral oil, petroleum-based fluids, and water-glycol hydraulic fluid systems; temperature rated from -40°F to +250°F
- 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 6µm, this element is targeted at the particle range that directly threatens servo and proportional valve performance — spool clearances in these valves are 5–13µm, making 6µm the critical filtration threshold for systems demanding ISO 4406 Class 15/13/10 fluid cleanliness or better. The L8 body’s expanded media area means lower differential pressure at higher flow rates, sustaining that cleanliness level without premature bypass valve opening.
6µm Buna-N in the high-flow L8 body: the specification for centralized HPUs and large multi-valve machine tool circuits running mineral oil where servo valve protection and extended filter service life are both priorities.

About the Pall HC7500SCN8H
The HC7500SCN8H is specified for high-flow industrial hydraulic power units — large transfer presses, multi-station machine tools, automated assembly systems, and heavy industrial machinery where servo or proportional valve circuits demand 6µm filtration and the flow rates involved would quickly load an L4 element. The long body and Buna-N seal combination suits standard mineral oil systems where maximizing filter life and minimizing maintenance intervals are the primary engineering goals.
