Envelope interchange · 3.66×5.79 in
93×147 mm filter elements
25 elements from 3 brand(s) share this envelope: 93 mm outside diameter and 147 mm overall length (3.66×5.79 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.

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 93×147 mm filter elements interchangeable?
They share the same physical envelope — 93 mm OD and 147 mm length (3.66×5.79 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 25 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.
