  • Key functions & working principle
Working Principle1. Hydraulic oil is pressurized by the machine’s hydraulic pump (up to 35 MPa) during equipment operation.
2. The 421-03-32170 hose acts as a conduit, transporting the high-pressure oil from the pump to actuators (cylinders, motors) or control valves.
3. The 4-wire spiral reinforcement counteracts internal pressure, preventing the hose from expanding or failing.
4. The outer cover protects the reinforcement and inner tube from external damage, while the NBR inner tube ensures compatibility with hydraulic oil.
5. The hose flexes to accommodate movement of hydraulic components (e.g., excavator boom lifting) without restricting oil flow.
Core Functions1. High-Pressure Oil Conduction: Delivers pressurized hydraulic oil to power critical equipment functions (digging, lifting, steering), enabling heavy-load operation.
2. Leak Prevention: Factory-crimped fittings and durable inner tube prevent hydraulic oil leakage – oil loss reduces system pressure, impairs performance, and creates safety hazards (slippery surfaces).
3. Component Protection: Shields internal hydraulic components (pumps, valves) from contamination by blocking debris entry through damaged hoses.
4. Environmental Adaptability: Withstands extreme temperatures, ozone, and weather – reliable in hot deserts, cold winters, and humid job sites.
