Problems solved by technology

[0002] Rubber fasteners are needed on automobile air-conditioning pipes, which can play the role of cushioning and shock absorption, and can play a good role in protecting air-conditioning pipes. At present, the existing rubber fasteners include the main body of the fastener and the fastening parts. The softness, hardness and tensile strength requirements of the two parts are relatively strict. At the same time, the degree of adhesion between the two parts is also quite high. Otherwise, the fasteners are prone to cracking and breaking, which greatly affects the product. The service life of the car air-conditioning tube also has a certain degree of impact on the service life and safety of use
