Hydraulic Hose Assembly

Product Specifications

Technical details and manufacturing context for Hydraulic Hose Assembly

Definition

A hydraulic hose assembly is a pre-assembled component used in hydraulic systems to transmit pressurized fluid between pumps, valves, actuators, and other elements. It consists of a flexible inner tube made of synthetic rubber, reinforced with one to four layers of braided or spiraled steel wire, and covered with a weather-resistant rubber outer layer. Permanent metal fittings, typically made of zinc-plated carbon steel (C45E), are attached to both ends to ensure leak-proof connections. The assembly accommodates movement and vibration while maintaining structural integrity under high pressure. Key parameters include nominal diameter (6–51 mm per ISO 4397), working pressure (1.0–42 MPa per ISO 1436), burst pressure (4.0–168 MPa), temperature range (-40 to 100°C for standard nitrile rubber), minimum bend radius (50–300 mm), length tolerance (±1.5% per ISO 1307), and leakage rate (0 mL/min at working pressure per ISO 19879). Weight ranges from 0.3 to 8.5 kg/m depending on size and reinforcement. These values are directory references and must be verified for the specific model and application. The assembly is used in machinery and equipment manufacturing, and its selection depends on system pressure, flow rate, fluid compatibility, and environmental conditions. Proper installation and routing are critical to avoid kinking and premature failure. Regular inspection for cover damage, fitting corrosion, or leakage is recommended. Always confirm model-specific values and standards with the legal manufacturer or supplier.

Working Principle

Hydraulic hose assemblies transmit pressurized hydraulic fluid from one component to another. The flexible hose absorbs movement and vibration while the steel wire reinforcement provides strength to withstand high pressure. The fittings create secure, leak-proof connections that maintain system pressure. The assembly must be selected based on working pressure, temperature, and bend radius to ensure safe operation. Over time, wear, abrasion, or improper routing can lead to failure, so regular inspection is necessary.
