Envelope interchange · 3.70×12.60 in
94×320 mm filter elements
4 elements from 2 brand(s) share this envelope: 94 mm outside diameter and 320 mm overall length (3.70×12.60 in).
Dimensional interchange — verify before substituting. These cartridges fit the
same bowl space; they are not guaranteed drop-in equivalents. Compare grade,
end caps, seals, collapse rating and bypass configuration for the specific duty.
| Model | Brand | ID (mm) | Micron | β rating | Collapse (bar) | Bypass | Seal | Type |
|---|---|---|---|---|---|---|---|---|
| 4.14.13 D 10 BN4 /-V | HYDAC | 44.7 | 10 | β10 > 1000 (HYDAC grade convention: β12(c) ≥ 1000) | 20 | housing | Fluorocarbon (Viton) | pressure |
| 4.94.300 D 10 BN4 | HYDAC | 48 | 10 | β10 > 1000 (HYDAC grade convention: β12(c) ≥ 1000) | 20 | housing | Nitrile (Buna-N) | pressure |
| HF29251 | Fleetguard | 48.6 | — | 3 µm at β200(c); 4.5 µm at β1000(c) per ISO 16889 | — | housing | — | inline |
| HF29252 | Fleetguard | 48.6 | — | 9.9 µm at β200(c); 12.4 µm at β1000(c) per ISO 16889 | — | housing | — | inline |
Substitution verification checklist
- Filtration grade. Compare at the same ISO 16889 Beta test point — “10 µm nominal” and “12 µm β1000” may be the same physical media.
- End caps & O-rings. Open/closed cap style and seal position block interchange even with identical OD/length.
- Seal compound. NBR is standard for mineral oil; phosphate-esters, high temperatures or bio-oils can demand fluorocarbon.
- Collapse rating. Low-collapse (~20 bar) return elements must never replace high-collapse (210 bar) pressure elements.
- Bypass strategy. Integral bypass valves (e.g. 3.4 bar) vs reusable housing valves change cold-start behaviour.
Frequently asked questions
Are all 94×320 mm filter elements interchangeable?
They share the same physical envelope — 94 mm OD and 320 mm length (3.70×12.60 in) — so they fit the same bowl. Interchangeability ends there: micron/Beta rating, end-cap geometry, seals, collapse rating and bypass configuration differ across the 4 elements listed and must be checked against the duty.
Is it a drop-in replacement if the OD and length match?
Only after verification. Confirm in order: (1) the filtration grade meets the ISO 4406 cleanliness target at the same Beta test point, (2) end-cap and O-ring arrangement is identical, (3) seal compound suits the fluid (NBR vs fluorocarbon), (4) collapse/burst rating fits pressure-line or cold-start conditions, and (5) the bypass strategy (integral valve vs housing valve) matches.
