FONHO manufactures this Caterpillar hydraulic filter as a direct OEM-quality replacement for part number 420-9748. It is built for Caterpillar trucks and equipment applications, matching the original specification for fit, sealing and filtration performance.
Hydraulic systems on construction and agricultural machinery are extremely sensitive to particle contamination — most pump and valve failures trace back to dirty oil. This hydraulic filter maintains the cleanliness class the system requires, protecting pumps, spools and cylinders.
