Product features

Hydraulic hose EN856 4SP and EN856 4SH are high pressure steel wire spiraled hydraulic hose consists of three layers. Inner tube, reinforcement and outer layer. Its used to deliver hydraulic fluid, petroleum based hydraulic fluid, hydraulic oil, mineral oil, gasoline, fuel oil, lubricating oil, emulsion, glycol solution, air brake, gas and water. Its mainly used in extremely high pressure and tough working conditions. Hydraulic hose EN856 4SP inside diameter size range is from 1/4 inch to 2 inch that is a wide size range relative to high pressure. Hydraulic hose EN856 4SH inside diameter size is from 3/4 inch to 2 inch with heavy duty workplace.

High pressure hose steel wire reinforced hydraulic rubber hose can be used in mine hydraulic support, oil field development, suitable for engineering construction, lifting and transportation, etc.

The hydraulic hose has three layers of different material structure. The inner tube is made from oil resistant synthetic rubber, therefore it can’t be corroded by the petroleum base fluid and liquid. The reinforcement part is consist with four layers of high tensile and high strength spiraled steel wire, and wind in alternating directions, therefore the hose can withstand internal and external extremely high pressure. The cover is made from high quality rubber and to play the protective function, so the rubber hose could resistant to abrasion, corrosion, air oxidation, extreme weather, ozone, aging, sunlight and cutting, also with longer service life.
