7Y-1941 Middle Radiator Hose supports E320B coolant transfer for B2B excavator parts repair, replacement stocking, and wholesale sourcing.
The 7Y-1941 Middle Radiator Hose YNF19138 is supplied for compatible E320B excavator cooling systems. It is positioned within the middle section of the coolant circuit, where engine coolant is transferred between corresponding radiator and engine cooling connections.
Radiator hoses are exposed to hot coolant, vibration, pressure cycling, and repeated temperature changes during machine operation. Over time, the original hose may become hardened, swollen, cracked, or weakened around the clamping areas, increasing the possibility of coolant leakage and machine downtime.
For B2B buyers, the 7Y-1941 Middle Radiator Hose should be verified by part number, E320B machine reference, molded routing, overall length, bend positions, connection diameters, and existing-hose photos. Middle coolant hoses can resemble upper or lower hoses while using different bends and connection sizes. Accurate comparison before bulk purchasing helps reduce incorrect inventory, installation delays, customer claims, and repeat freight.

Q: Is 7Y-1941 an upper radiator hose?
A: No. It is identified as the middle / center radiator hose.
Q: What should be checked before ordering?
A: Part number, machine model, molded shape, bends, connection diameters, length, and existing-part photos should be verified.
Q: Can related cooling hoses be ordered together?
A: Yes. Upper, middle, and lower hoses can be consolidated with radiators and other cooling-system components.
YNF Machinery supplies 7Y-1941 middle radiator hoses and related E320B cooling-system parts for excavator workshops, fleet operators, machinery dealers, wholesalers, and international importers.
The YNF19138 center coolant hose is a molded and fitment-sensitive replacement part. For professional B2B buyers, the part number should be checked together with hose shape, bend positions, connection diameters, and overall dimensions before quantity purchasing.
Buyers can provide the 7Y-1941 reference number, E320B machine information, required quantity, hose-end measurements, installation photos, and clear images of the removed hose for fitment confirmation.
Upper radiator hoses, lower radiator hoses, radiators, coolant reservoirs, water pumps, thermostats, radiator caps, and cooling fans can also be consolidated into the same inquiry to simplify procurement and reduce fragmented international shipment costs.
