4SH hose structure consists of three parts: tube, reinforcement, and cover
Tube
Black, oil resistant synthetic rubber
Reinforcement
Four high tensile steel wire spirals, making the hose highly resistant to high pressure.
Cover
Black Color, Synthetic rubber resistant to oil, weather, and abrasion
Hydraulic Rubber Hose EN 856 4SH conveys hydraulic fluid to or among hydraulic components, valves, actuators, as well as tools. Typically it is flexible and often reinforced. Usually, the hose is constructing with several layers of reinforcement. Hydraulic systems frequently operate at high or very high pressures. Therefore, dimensions, performance specifications, construction options, and features are important parameters to consider when searching for a hydraulic hose.
Construction options for hydraulic hoses include reinforced, coiled, corrugated, or convoluted. The reinforced hose is constructing with different reinforcement styles such as textile braid, wire braid, wire helix, and other designs in many plies or layer configurations.
The most common use primary materials for hydraulic rubber hoses include elastomers, fluoropolymers and silicone, thermoplastics, metal, and composite. Similarly, you can select elastomeric or rubber hydraulic hose for their flexibility. Also, fluoropolymer hose offers good flex life, superior chemical and corrosion resistance. It can also handle high temperatures. Finally, the thermoplastic hydraulic hose offers a tight minimum bend radius.
