PART DESCRIPTION

The Kubota RD451-51930 O-Ring is a genuine OEM sealing component used in fuel water separators and fuel separators across a broad range of Kubota compact excavators and agricultural tractors. This O-ring is installed within the separator housing assembly to ensure a tight, leak-free seal between separator components, preventing fuel leakage and air intrusion into the fuel system.

It is catalogued under “Water Separator (Component Parts)” or “Separator [Component Parts]”, depending on the machine series.
