Title
FILTER (KU-RD46162120)
Description
The Kubota KU-RD46162120 Hydraulic Return Filter is a genuine OEM filtration component designed to keep Kubota hydraulic systems clean, protected, and operating efficiently. Installed in the hydraulic return circuit, it captures dirt, metal particles, sludge, and other contaminants before the oil returns to the reservoir.
As a result, the filter helps reduce wear on pumps, valves, cylinders, and hydraulic motors. Furthermore, cleaner hydraulic oil improves system responsiveness, maintains smooth machine operation, and supports longer component life.
Built to Kubota’s exact specifications, the RD46162120 features high-efficiency filtration media and a durable heavy-duty housing for reliable performance in demanding construction and excavation environments. Consequently, it delivers strong contaminant retention while maintaining stable hydraulic oil flow under heavy workloads.
In addition, regular replacement helps minimise downtime, reduce maintenance costs, and preserve overall hydraulic system reliability. Whether used for scheduled servicing or preventative maintenance, this genuine Kubota filter provides dependable fitment and OEM-quality protection.
