High Quality MaterialsBearless single ear hose clamps are made of 304 austenitic stainless steel, with good corrosion resistance and TUV certification. 360 Bearingless Non-bearing single ear hose clamps provide even compression of the pipe surface and ensure 360 degree tightness. Cochlea DesignThe "cochlea" structure design strengthens the function reinforcement and provides a powerful thermal expansion compensation function. Thus, the variation in size caused by the temperature change of the pipe can be compensated, and the pipe fitting will always be in a good sealing and fixing condition. Hose ClampLong 24cm , with a maximum mouth opening of 23mm, are efficient and labor-saving thanks to the lever principle. The cutting pliers mouth made of chrome vanadium steel, not easy to crack or deform. In addition, it is equipped with anti-rust lubrication system for maintenance.
