Buy HITACHI EX120-2 OIL COOLER HOSE PIPE (HYD PUMP TO VALVE CHEST) (OEM HI 4323031) | Tonkee®

The primary function of this hose pipe is to transport hydraulic fluid from the hydraulic pump to the valve chest within the excavator's hydraulic system.

The hydraulic pump is responsible for pressurizing the hydraulic fluid, while the valve chest regulates the flow and direction of the fluid to control the various hydraulic functions of the excavator, such as the operation of the boom, arm, and bucket.

The OEM designation, HI 4323031, indicates that this hose pipe is manufactured by Hitachi, the original equipment manufacturer of the excavator. This OEM status ensures that the hose pipe is designed to meet the exact specifications and quality standards required for optimal performance and durability in the Hitachi EX120-2 excavator.

One of the critical factors in the design and construction of this hose pipe is its resistance to hydraulic fluid, which can be under high pressure and temperature.

The materials used in its construction must be able to withstand these conditions to prevent leaks or failures that could result in a loss of hydraulic power and potential damage to the excavator.

The hose pipe is typically made from high-quality rubber or synthetic materials that are reinforced with layers of fabric or steel wires to provide strength and durability. This construction ensures that it can handle the demands of the hydraulic system and remain flexible enough to accommodate movement within the excavator's components.

Proper installation and maintenance of the oil cooler hose pipe are crucial to its performance and longevity. Regular inspections are essential to check for signs of wear, damage, or deterioration. Any issues should be addressed promptly to prevent hydraulic fluid leaks or interruptions in the excavator's operation.
