21N-62-36780 Hydraulic Hose Assembly Description
The 21N-62-36780 Hydraulic Hose Assembly is a heavy-duty hydraulic spare part designed for Komatsu PC400-7 and PC450-7 excavator hydraulic systems. It is used to transfer high pressure hydraulic oil between hydraulic components, ensuring stable power transmission and reliable machine operation.
Manufactured with reinforced rubber layers and durable fittings, this Komatsu excavator hydraulic hose provides excellent flexibility, pressure resistance, and sealing performance. The assembly structure allows the hose to withstand continuous vibration, pressure fluctuations, and harsh construction environments.
For large excavators, hydraulic hose performance directly affects working efficiency and maintenance reliability. Aging or damaged hoses may cause hydraulic oil leakage, pressure loss, and unexpected machine downtime. Replacing worn hydraulic hose assemblies helps maintain stable hydraulic performance and improve equipment availability.
The YNF18462 and YNF18466 21N-62-36780 hydraulic hose assemblies are supplied by YNF Machinery for excavator parts wholesalers, repair companies, and construction machinery distributors requiring reliable aftermarket hydraulic solutions.
