1.Highquality materials: High precision single ear stepless hose clamps are Made of 304 Stainless Steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, a good choice for longterm use.Hose clamps are used to seal various types of hoses. This materials ensure that adjustable hose clamps can be used for a long time in complex environments. 2.360°Stepless Seal: Narrow band design providing a more concentrated sealing pressure; The cochlear design provides a powerful thermal expansion compensation function, which compensates the dimensional change of the pipe due to temperature changes, so that the tube is always in a well sealed and fastened state. 3.: The slide ear clamp ring onto the tube, push the pipe onto the fitting and squeeze it with a clamp tool. Provide a firm, leak and reliable crimp joint connection. 4.Scope of Application: These single ear hose clamps used in all plumbing system and in securing hoses, pipe, cable, tube, fuel lines etc.Suitable for soft and hard pipe connection on pipeline conveying equipment of automobile, train, ship, medical equipment, petrochemical industry, water supply system, various beverage machines.
