Problems solved by technology

Since the connecting pipe in the power steering gear belongs to the high-pressure series and has been in contact with the fuel for a long time, its stability and reliability are related to the safety of the car and the person, so its technical content and standard requirements are getting higher and higher. However, the current Power steering hose products are far from meeting people's development needs for the modern automobile industry in terms of heat resistance, oil resistance, pressure resistance, aging resistance, pulse performance, product qualification rate and cost.
