A crimping assembly is disclosed. The assembly includes cam profiles (72, 74 , 76) on the ends of the arms. The cam profiles (72, 74, 76) are engaged by th e crimping tool and control the input force versus displacement of the tool. T he cam profile includes a first portion (72) defined by a radius, a second portion (74) adjacent the first portion and defined by a non-linear equation , and a third portion (76) adjacent the second portion and defined by a linear equation. The assembly further includes a passive mode of failure in the sid e plates (130). The arms (110) of the assembly have a hardness greater than th e side plates (130) and have a maximum section height at their point of rotati on for increasing their strength. The assembly further includes a leaf spring (150) disposed between the arms and held therebetween by pins (160) disposed in holes defined in the sides of the arms. A crimp ring having an increased diameter is disclosed for reducing the crimping force required to crimp 3-in ch fittings.
