High-pressure Hose

Applicable for the working temperature from -40℃ to 100℃, the high-pressure hose is generally applied for transmitting hydraulic power or conveying high pressure medium, for example water, gas, oil, etc. Made of newly-developed nano material, the high pressure rubber hose has remarkable oil resistance, ozone resistance, anti aging performance, and pulse performance. The high-pressure hose includes reinforced steel wire braided hose and reinforced steel wire twined hose.
