Hydraulic Rubber Hose EN856 4SP

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.

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℃)

                                                                                  Specification

Standard : EN856 4SP

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.

Laboratory:  

Strong quality control team, advanced laboratory. 
Before the mass production, test each batch of raw material. 
After the production, test each hose to guarantee a 100% qualification. 
Each hose tested at 2 times of working pressure. 
We do everything possible to supply good quality goods for our customer.

Special packing is available according to customers’ requirements.
