1. Fasten the connector, used to fix the hose and the joint so that the gas or liquid can be safely transmitted without leaking. 2. 360-degree clamping, resistance to thermal expansion and contraction, the surface is treated with color zinc plating, which is not easy to rust and has a long service life. 3. With spring double ring structure, it has better fastening effect. 4. Scope of application: widely used in motor vehicles, machine tools, trains, ships, aviation, petroleum, chemical, pharmaceutical, mining, sewage treatment, purification projects and gas pipelines. 5.
