Description
Overview:
This Water Pipe 3 is a genuine Kubota cooling hose for selected mini excavators, including the KX61-3 and KX71-3. It routes engine coolant between components in the cooling circuit to control operating temperature and prevent overheating under load. The hose is a moulded, heat‐resistant black rubber pipe with factory‐formed bends for a precise fit and reliable flow. Built for the vibration and thermal cycles seen on compact excavators, it maintains seal integrity when clamped correctly and used with the specified coolant. Supplied as a direct replacement for OEM No. 1G680‐72870, it restores OEM routing and performance with no modifications. Suitable for routine servicing or repairs on Kubota mini excavators working in construction, utilities, landscaping and hire fleets.
