Product details

Rubber connection hose on the car can be roughly divided into three categories: low-pressure hose, high-pressure hose and oil-resistant hose. Although the structure of the hose is different, but roughly by the inner rubber layer, reinforcing layer and outer rubber layer and other three basic parts. The inner rubber layer is the working layer of the hose in contact with the medium, plays the role of sealing medium, protect the role of the reinforcement layer, it is subjected to long-term transport medium of immersion, corrosion and friction, in order to meet the needs of the work, the requirements of the inner rubber layer has a certain thickness, can be resistant to temperature, corrosion, friction, a certain degree of airtightness, flexibility and strength. Enhanced layer is the part of the hose to withstand pressure, but also to give the entire hose to the necessary stiffness and strength. The outer rubber layer is the protective layer of the hose, due to the contact with the external environment, not only requires it to be wear-resistant and have a certain thickness, but also requires a certain degree of erosion resistance and aging resistance.
