A hydraulic hose is specifically designed to convey hydraulic fluid to or among hydraulic components, valves, actuators, and tools. It is typically flexible, often reinforced, and usually constructed with several layers of reinforcement since hydraulic systems frequently operate at high or very high pressures. Hydraulic hose is used in a variety of industrial hydraulic systems. Dimensions, performance specifications, construction options, and features are important parameters to consider when searching for hydraulic hose.
Important dimensions for the selection of hydraulic hose include the inside diameter, outside diameter, and minimum bend radius. Hydraulic hose sizes are denoted by the inside and outside diameter of the hose. The inside diameter refers to the inside of the hose or liner. The outside diameter is often a nominal specification for hoses of corrugated or pleated construction. Minimum bend radius is based on a combination of acceptable hose cross-section deformation and mechanical bending limit of any reinforcement.
