Distributor checklist

  • Confirm OEM number, replacement number, machine model and engine model.
  • Check height, OD, ID, thread, gasket and water-drain structure.
  • Agree packaging, label, MOQ, sample approval and private-label requirements.

Use the Filter Cross Reference Guide as a starting point, then verify against the real machine. Brand names and part numbers are used only for replacement identification.

Truck sourcing notes

This Truck article supports practical filter selection by connecting operating conditions, replacement references, product categories, and sourcing questions in one place.

Use the guidance together with equipment model, duty cycle, dust level, fuel quality, oil interval, and hydraulic system requirements to narrow down suitable GUOHAO filter options.

When requesting a quotation, include the current part number, target quantity, photos, dimensions, packaging preference, and destination market so the team can confirm samples and delivery planning.
