Problems and solutions for flexible metal hose
As one of the most important means of transportation, cars play an important role in our lives. With the innovation and development of the automotive industry, cars are no longer so out of reach. Therefore, more and more people own their own cars. In cars, brake hoses play an important role. Brake hoses are updated frequently and have a large market demand.

True: The tube body is designed according to the original car with three layers of rubber plus two layers of fiber, 5 layers of tube body, good pressure resistance, and not easy to burst.
False: The tube body has two layers of rubber and two layers of fiber or two layers of rubber and one layer of fiber, poor pressure resistance, easy to burst, and there are safety hazards.
Production process standards
True: The brake hose is developed completely according to the original car size oe, and the data size and appearance are consistent with the original car. And a secondary screening will be carried out before production to eliminate defects.
False: The thread of the joint has errors or defects, and there is a risk of oil leakage. After the brake hose is buckled, it cannot be ensured that each brake hose is qualified.
Service life
