Komatsu 21T-979-6220 Heavy Duty Hydraulic Hose Assembly

Komatsu 21T-979-6220 Heavy Duty Hydraulic Hose Assembly is a replacement hose assembly for Komatsu heavy equipment. Identified by the part number 21T-979-6220, this assembly is used to carry hydraulic fluid between components in a machine’s hydraulic system, enabling the operation of hydraulic functions. In hydraulic systems, hoses like this provide the flexible conduits that connect pumps, control valves, and actuators to support lifting, digging, steering, and other machine movements. As a heavy‑duty component, it is designed to withstand the demanding service conditions of construction and industrial equipment, helping to maintain steady fluid transfer and ride out intervals of heavy use. This part is intended to replace hoses that have worn, cracked, or leaked, restoring hydraulic circuit integrity and reducing downtime on worksites that rely on Komatsu equipment.
