Hose

Our high pressure hose is used to transportwater, gas, oil and other high pressure mediums. It can operate at -40℃to 100℃. Thistype of hose adopts advanced nano material so that itfeatures great oil, ozone, aging resistance and high pulse performance. Our high pressure hoses includetwo types, which are enhanced steel wire braided hydraulic hose and enhanced steelwire spiral hydraulic hose.
