Convert any Caterpillar (CAT) filter part number to a FONHO replacement. We manufacture direct equivalents for CAT 1R-series spin-on filters and dash-number fuel, oil and hydraulic filters — including popular numbers such as 1R-0750, 1R-0749, 1R-0762 and 1R-0726. 92 cross references from our catalog are listed below, all produced under IATF 16949:2016 certified processes as an OEM and private-label filter manufacturer.
No match in the table — send us your CAT number, we cross reference thousands more applications.
How CAT Filter Numbers Work
1R-XXXX — Caterpillar Advanced Efficiency spin-on filters, covering fuel (1R-0750, 1R-0762), oil (1R-0716, 1R-0726) and water separators;
XXX-XXXX (dash numbers) — newer CAT part-number format for fuel filter assemblies, hydraulic and HEUI filters (e.g. 326-1642, 361-9554, 465-6506);
Letter-prefix numbers — legacy CAT codes such as 9T-6636 and 7W-2326 for hydraulic and lube elements.
The same CAT element usually also carries a Fleetguard FS/FF/LF number, a Baldwin BF/B number and an OEM engine number — our table shows the main crosses, and every FONHO product page lists the full set with dimensions and applications. Search any Caterpillar filter number above, or use our full filter cross reference lookup.
Frequently Asked Questions
Are FONHO replacements equal to genuine CAT filter quality?
Our CAT-equivalent filters meet or exceed original specifications for filtration efficiency, burst pressure and dust-holding capacity. As an IATF 16949:2016 certified factory we supply fleet and distributor customers with test reports on request. FONHO is an independent manufacturer; all CAT and Caterpillar numbers are shown for cross-reference identification only.
Which CAT fuel filters do you cover — is 1R-0750 available?
Yes. 1R-0750, 1R-0749, 1R-0762 and 1R-0771 CAT fuel filters are in stable production, along with the dash-number fuel filter assemblies (326-1642, 361-9554, 228-9130). Send us your CAT number for a verified cross reference and quotation.
My CAT number is not in the table — can you still supply it?
Very likely. This table lists our fastest-moving Caterpillar cross references; our full catalog covers many more construction-machine and engine applications. Send us the CAT number and we will confirm the equivalent within 24 hours.
Can you produce CAT-equivalent filters under our own brand?
Yes — private label is our core business. We handle shell printing, custom packaging and barcoding, with flexible MOQ so wholesalers can mix CAT-equivalent oil, fuel and hydraulic filters in one container. Standard bulk orders ship in 25–35 days.
