Ideal for: high pressure and high impulse hydraulic system. This is the most flexible EN 856 4SH hydraulic hose in industry with superior impulse performance (tested to 1,000,000 impulse cycles at bend radius lower than EN 856 Standard). It’s ideal for hydraulic fluids like synthetic esters and polyglycols. It’s also ideal for vegetable oils and petroleum based fluids.
Tube: Black and oil resident synthetic rubber (Nitrile)
Reinforce: 4 layers of spiraled and high tensile steel wire.
Cover: Black, oil, abrasion and weather resistant synthetic rubber.
Temperature Range: -40℃ (-104 ℉ ) to +100℃（+212 ℉）
EN 856 4SH Application:
DIN EN 856 4SH can be used for forklift and hydraulic engine. It’s also ideal for oilfield extraction machinery, mine machinery and so on.
Raw Material:
Import LANXESS NBR from Germany, which is the highest quality rubber in the world
Import BELKTA steel wire with high tensile strength 2750 Mpa from Belgium.
Good quality materials make our hose perform well
Factory Workshop:
Our spiral machine is 100% servo electronics control, which is from Japan engineer team’s master work.
High length control accuracy, tolerance < 0.001.
High rubber content> 47%, impulse>500,000 circles.
Laboratory:
Our factory has strong quality control team and we set up advanced lab.
Before the mass production, we test each batch of raw material
After the production, we test each hose to make sure a 100% qualification.
Each hose is tested 2 times on working pressure.
We do everything to supply good quality goods to you.
After finishing the Hydraulic Hose production, we will pack the hose. In general, the packing will
use woven bag and plastic film. Special packing is available according to customers’ requirements.
