Recommended For: Extremely high pressure and high impulse hydraulic applications. It 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, vegetable oils and petroleum based fluids.
Tube: Black and oil resident synthetic rubber (Nitrile)
Reinforcement: Four alternating layers of spiraled and high tensile steel wire.
Cover: Black, oil, abrasion and weather resistant synthetic rubber.
Temperature Range: -40℉ to +250℉ (-40℃ to +121℃)
Products Application :
DIN EN856 4SP can be used for forklift, hydraulic engine, oilfield extraction machinery, mine/road/construction machinery, especially for some high pressure machine.
Importe LANXESS NBR from Germany, which is the highest quality rubber in the world
Importe BELKTA steel wire with high tensile strength 2750 Mpa from Belgium.
Good quality materials provide our hydraulic hose steady performance, good decentrality and excellent oil resistance.
Our spiral machine is 100% servo electronics control, which is Japan engineer team’s master work.
High length control accuracy, tolerance < 0.001 .
High rubber content> 47%, superior impulse performance, impulse>500,000 circles.
Our factory has strong quality control team and we set up advanced laboratory.
Before the mass production, we test each batch of raw material
After the production, we test each hose to guarantee a 100% qualification.
Each hose is tested 2 times on working pressure.
We do everything possible to supply good quality goods to our customer.
After finishing the Hydraulic Hose production, we will pack the hose. In general, the packing could be woven bag and plastic film. Special packing is available according to customers’ requirements.
