KSH0777 Upper Radiator Hose supports SH300A1 coolant circulation for B2B excavator parts repair, replacement stocking, and wholesale sourcing.
The KSH0777 Upper Radiator Hose YNF19016 is supplied for compatible SH300A1 excavator engine cooling systems. It is positioned in the upper section of the cooling circuit, where heated engine coolant is transferred toward the radiator for heat dissipation.
During continuous machine operation, the hose is exposed to hot coolant, pressure cycling, engine vibration, and repeated temperature changes. An aging hose can become hardened, swollen, cracked, or weakened around its clamping areas, increasing the possibility of coolant leakage and unexpected downtime.
For B2B buyers, the KSH0777 Upper Radiator Hose should be verified by part number, SH300A1 machine reference, overall molded shape, hose length, bend orientation, inlet and outlet diameters, and existing-part photos. Since molded coolant hoses can look similar while using different routing geometry, physical comparison is recommended before bulk purchasing to reduce incorrect inventory, installation delays, customer claims, and repeated freight.

Q: Which excavator is referenced?
A: The supplied machine reference is SH300A1.
Q: Where is KSH0777 installed?
A: It is used in the upper section of the compatible engine cooling circuit.
Q: Is this the lower radiator hose?
A: No. This product is identified as the upper radiator hose.
YNF Machinery supplies KSH0777 upper radiator hoses and related SH300A1 cooling-system parts for excavator workshops, fleet operators, machinery dealers, wholesalers, and international importers.
The YNF19016 upper coolant hose is a molded and fitment-sensitive replacement part. For professional buyers, the reference number should be checked together with hose routing, bend positions, connection diameters, and overall dimensions before quantity purchasing.
Buyers can provide the KSH0777 part number, SH300A1 machine information, required quantity, hose-end diameters, overall measurements, installation photos, and clear images of the removed hose for fitment confirmation.
Lower radiator hoses, radiators, coolant reservoirs, radiator caps, thermostats, water pumps, cooling fans, and other SH300A1 cooling-system components can also be consolidated into the same inquiry to simplify procurement and reduce fragmented international shipping costs.
