Hydraulic Rubber Hose EN856 4SP

 

Four Layers Steel Wire Spiral High Preessure Hydraulic Hose

EN 856 4SP steel wire spiraled hydraulic hose is suitable for mine hydraulic support and the related equipment. The hose is resistant to flame and static. It is almost similar to EN 856 4SH steel wire spiraled hydraulic hose in structure, but it can bear higher working pressure than EN 856 4SH steel wire spiraled hydraulic hose under the same temperature. It is composed of three parts: tube, reinforcement and cover. The tube is made from black oil resistant synthetic rubber, making the hose resistant to abrasion and corrosion. The reinforcement is made from four layers of high tensile and high strength spiraled steel wire which is specially designed for rubber hose, making the hose perfectly resistant to high pressure. The cover is made from high quality black synthetic rubber, making the hose resistant to abrasion, corrosion, cut, weather, ozone, oil and aging. More importantly, the appearance is cloth surface rubber. Therefore, the hose has longer service life.

Recommended For: Extremely high pressure and high impulse hydraulic applications. This hose is the most flexible EN856 4SP hose in the industry with superior impulse performance ( tested to 1,000,000 impulse cycles at bend radius lower than EN 856 Standard). Compatible with biodegradable hydraulic fluids like synthetic esters, polyglycols and vegetable oils as well as petroleum-based fluids.

INNER TUBE: oil resistant synthetic nitrile rubber.

REINFORCEMENT: 4 layers of steel wire spiral.

COVER: oil and weather resistant synthetic rubber.

APPLICATION: petroleum base and water base hydraulic fluids.

SURFACE: wrapped surface.

TEMPERATURE RANGE: -40℃ (-104 ℉ ) to +100℃(+212 ℉).

Standard: EN856 4SP
