I got lost about SY band, but I bought it because the price was cheap a bit. As a shape, it is a large version of metal fittings used for the air intake connection part of a car or the fixing part of a water spray hose. Since the shape is flat, it will crush the irregularities of the aluminum duct, but the occurrence of air leak has not occurred by it. However, the tightening torque increases as the contact area of the part to be tightened becomes larger than the SY band.
