Product application：suitable for large construction machinery such as excavators or demanding environments.
Inner rubber layer：Nitrile or neoprene synthetic rubber, suitable for biodegradable hydraulic oil
Reinforcement layer：one or two layers of steel wire weaving (1/4" ‒3/8"), pulse ≥300,000 times four layers of steel wire winding (1/2"‒2"), pulse ≥1 million times
Outer layer：non -stripping, wear-resistant, weather-resistant synthetic rubber
Temperature range：-40℃ to +100℃ (-40℉ to +212℉) -40℃ to +121℃ (-40℉ to +250℉)
Low bending：the bending radius is reduced by 30% compared with the ISO18752 standard; it is reduced by 38% compared with the SAE standard
High pressure：36% exceeding SAE standard
Long service life：Two-year warranty for integrated hose joints and hydrogenated nitrile seals provided by Litong for supporting use
