*Note: the minimum bend radius is determined by the inner side corrugated tube!
No bend radius is specifi ed in the part number, since it depends on travel and fi ll weight. The smallest specifi ed radius below is the minimum to guarantee the service life of
the cables. In most applications, however, the radius remains larger because the shape of the tube defi nes this.
