Typical equipment & applications

  • Replacement element for ARGO-HYTOS hydraulic filter housings
  • Mobile and industrial hydraulic circuits

Selection pitfalls — read before you substitute

  • “10 µm nominal” and “12 µm at β1000” can describe the very same media — one is reported at β≥200, the other at β≥1000 per ISO 16889. Compare ratings at the same Beta test point, not just the printed micron number.
  • Nitrile (NBR) seals are standard for mineral hydraulic oil but fail early in some phosphate-ester fluids and at sustained high temperature; verify seal compound against the fluid data sheet (fluorocarbon/Viton executions may be required).
  • End-cap geometry and the number/position of O-rings block interchange even when OD and length match — visually compare end caps before fitting, especially with aftermarket cartridges.

Frequently asked questions

What are the dimensions of the K3.1370-76K8 filter element?
The published envelope is 147 mm OD × 662 mm length with a 62 mm inside diameter (5.787 × 26.063 in × 2.441 in ID). Confirm against the housing drawing before ordering.
What micron rating does K3.1370-76K8 use?
This element is rated 10 µm (nominal class). Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.
What replaces the K3.1370-76K8 filter element?
Cross references are being verified for this model — use the inquiry form and the engineering desk will confirm equivalents.
How do I read the K3.1370-76K8 part number?
See the designation decoder above: each segment of AHK3137076K8 encodes size, line type, filtration grade and media/collapse execution.
Is a same-envelope aftermarket element always a drop-in replacement?
No. Matching OD and length only proves the cartridge fits the bowl. End-cap style, seal compound, micron/Beta rating, collapse pressure and bypass configuration must also match; the table above tags every equivalent as full, partial or verify for exactly this reason.
How often should a hydraulic return-line element be replaced?
Replace at the housing manufacturer’s recommended differential-pressure setting (commonly signalled by a clogging indicator), or on a time-based service interval when no indicator is fitted — never wait for bypass to open continuously, because unfiltered oil then reaches the valves.
