4SH hose structure is composed of three parts: tube, reinforcement and cover
Black, oil resistant synthetic rubber
Four high tensile steel wire spirals, making the hose highly resistant to high pressure
Black Color, Synthetic rubber resistant to oil, weather and abrasion
Hydroflex Hydraulic Rubber 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. Dimensions, performance specifications, construction options, and features are important parameters to consider when searching for hydraulic hose.
Construction options for hydraulic hose include reinforced, coiled, corrugated, or convoluted. Reinforced hose is constructed with some element of reinforcement—styles include textile braid, wire braid, wire helix, and other designs in many ply or layer configurations.
While hydraulic hose is usually constructed of multiple materials, the most commonly use primary materials include elastomers, fluoropolymers and silicone, thermoplastics, metal, and composite or laminated structures. Elastomeric or rubber hydraulic hose are often selected for their flexibility. Fluoropolymer hose offer good flex life, superior chemical and corrosion resistance, and can handle high temperatures. Thermoplastic hydraulic hose offer tight minimum bed radii and excellent kink resistance.
Most hoses are manufactured to SAE J517 or European Norm (EN) Standards, the latter based on earlier DIN German standards.
