Rubber hoses are prone to expansion and rupture. The hoses used in factories are made of low-cost natural rubber with poor mechanical properties, making them susceptible to expansion, leakage, and even bursting after prolonged use. Plastic flanges are also prone to breakage: the plastic connectors used in factories may break on their own during normal operation, leading to coolant leakage and engine overheating. Bevinsee offers a new solution to address these issues.
