EN standard hydraulic hose
EN standard hydraulic hose is another standard all over the world. It has different reinforcement structures, such as different braid or spiral layers to increase the pressure of hydraulic hose. Here are commonly used EN standard hydraulic hose, including structures, drawings, specs and applications.

They have the same cover and core. The core is oil and water resistant synthetic rubber, and the cover is black color synthetic rubber resistant to oil, water and ozone. It is composed of three parts: tube, reinforcement and cover. It is resistant to abrasion and corrosion due to the tube. And it can work well in high pressure environment thanks to its high tensile steel wire reinforcement. Besides, it is resistant to weather, ozone, aging and sunlight because of the cover with the cloth impression.
EN 853 1SN steel wire reinforced hydraulic hose has one-braid high tensile steel wire
EN 853 2SN hydraulic hose has two-braid high tensile steel wire.
EN 857 1SC hydraulic hose has similar performance with its counterpart SAE 100R1 besides tighter bending radius. It is reinforced by one-braid high tensile wire.
The reinforcement is made from two layers of high tensile steel wires, making the hose highly resistant to high pressure. Has smaller outside diameter
EN 856 4SH steel wire spiraled hydraulic rubber hose consists of an inner tube of oil resistant synthetic rubber, four spiral layers of spiral wires reinforcement and is covered with oil and weather resistant synthetic rubber.
EN 856 4SP hydraulic rubber hose is similar to EN 856 4SH hydraulic hose, but the working pressure (under the same working temperature) is higher than EN 856 4SH hose. Four-spiral high tensile spiral wire reinforcement structure gives the hose best abrasion resistance and impulse fatigue. This kind of reinforcement is ideal ...
