Unlike conventional ring tightening methods, this method gives a clean ring surface since it uses no swage and thus has no vertical or horizontal lines. The structure thus offers even tightening in a circular shape. Because the ring edges are horn-shaped, there is no scratching of the hose. As well, the seven different colors mean that each can be used for a different, easily distinguishable purpose. (Colors: Blue, red, yellow, green, purple, brown, orange)
*Silver is the standard color.
