LT SA6991
Scope of application：suitable for large construction machinery such as excavators or demanding environments.
Reinforcement layer：one or two layers of steel wire weaving (1/2" ‒3/4"), pulse ≥ 300,000 times, four layers of steel wire winding (1" ‒ 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 41% compared to the ISO18752 standard; 47% lower than the SAE standard
High pressure：exceed the SAE standard by 60%
Long service life：Two-year warranty for integrated hose joints and hydrogenated nitrile seals provided by Litong for supporting use
