Hydraulic Hose EN856 4SH

Recommended For:

Extremely high pressure and high impulse hydraulic applications. This hose is the most flexible EN856 4SH 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.

Application Fields:

Mine hydraulic support, oilfield extraction machinery, mine / road / construction machinery.

Tube:

Black, oil-resident synthetic rubber(Nitrile)

Reinforcement:

Four alternating layers of spiraled, high-tensile steel wire.

Cover:

Black, oil, abrasion and weather resistant, synthetic rubber.

Temperature Range:

-40℉ to +250℉ (-40℃ to +121℃)

Standard : EN856 4SH

Raw Material:

LANXESS NBR rubber from GERMANY ,this rubber has the best quality in the world.

BELKTA steel wire with high tensile strength2750Mpa from Belgium.

Good quality materials make our hydraulic hose steady performance, good decentrality and excellent oil resistance.

Factory Workshop:

• Spiral Machine is 100% Servo electronics control from Japan engineer team’s master work.

  The advantage of the machine is high length control accuracy with tolerance <0.001.

• High strength inner rubber.

  high rubber content >47%, superior impulse performance, impulse >500,000 circles.

In general, the packing will use woven bag and plastic film.
Special packing is available according to customers’ requirements.
