The what’s what ..and how and why ..on automotive hoses from Tieling Jinghua

Liaoning Jinghua Auto Parts (formerly the Tieling Jinghua Rubber Seal Components) is a thriving manufacturer of rubber products and automotive rubber hoses and flexible piping. It is located in Fanhe New Zone, close to the Tienling South Exit of Shenyang-Harbin Freeway. We are pleased to welcome this business to the IMD. 

The company was first established in 1983 and has produced its well-known range of varied sets and styles of automotive components for over 20 years.  Here, compliments of this expert ‘hoses’ company is a blog summary of automotive rubber tube and hose types and their value and usage advantages to the automotive industry today

natural advantages 

As they point out hose is widely used in wide-ranging industrial production in general due to its natural advantages. With the needs of modern life today, the types of hoses are constantly increasing. The hose market in the automotive industry has always received much attention. Although automotive hoses in terms of types is relatively limited, it is representative of the hose industry…… below is some potted information from this expert specialist company on the automotive hoses ‘line-up’ ….

Air conditioning hose

In the past two years, China’s automotive air-conditioning hoses have developed rapidly, and the number of enterprises producing and researching new rubber hoses has gradually increased. There are two technical problems to be solved in developing high-quality air-conditioning hoses. The first is the pollution of air-conditioning hoses, and the second is the leakage of fluorine-free hoses. Protecting the environment starts from small things, and it is the responsibility of everyone to optimise our automotive air conditioning hoses.

Radiator hose

High-grade EPDM rubber is used as the main material of the radiator hose, and special synthetic fiber knitting reinforced structure is selected. The cold-feed extrusion technology and the coreless pre-formed bare die vulcanisation new process, which are the first in China, are successfully manufactured Automobile radiator hoses with technical indicators such as breaking strength, ozone resistance, and adhesion strength meeting international standards.

Fuel hose

The inner rubber layer is composed of fluoroelastomer and chlorohydrin rubber, and the outer rubber layer is chlorohydrin rubber. The difference is that the reinforcement layer uses aramid fiber. According to related reports, domestic production of composite fuel hoses for automobiles has been used in Santana, Audi, Jetta, Fukang, POLO and other cars.

Brake Hose

Brake hose is an important part of a car with very strict quality requirements, which is related to the safety of the vehicle and people. In addition to being resistant to brake fluid, the brake hose must also have good aging resistance and moisture permeability.

Power steering hose

Power steering hoses are more stringent in automotive hoses. There are two specific requirements. One is good heat resistance and the other is to prevent corrosion of oily substances. This has caused some contradictions. The steering hose using fluorine rubber has good heat resistance, but because the fluorine rubber tube easily reacts with certain additives in the oil, its application is limited. Therefore, many car enthusiasts often have strict requirements on the steering hose of the car.

 Turbocharger hose

Turbocharger hoses are mainly suitable for racing cars and sports cars. In recent years, due to consumer demand, development of ordinary cars has begun. China’s turbocharger hoses are still in the research and development stage and have a good development momentum.
