Compression jaw set with failure mode preventing reuse

Abstract

A jaw arm for an associated compression tool having cam rollers that displace forwardly and rearwardly along an axis to pivot the jaw arm includes a recess and a notch. The recess is disposed adjacent a forward end of the jaw arm. The notch is axially spaced rearwardly from the recess. The recess is configured to receive an associated pipe and an associated coupling for compressing at least one of the associated pipe and the associated coupling to mechanically attach the associated pipe to the associated coupling when the jaw arm is pivotally displaced toward at least one of the associated pipe and the associated coupling. The notch is configured to receive an associated cam roller of the associated compression tool and to retain the associated cam roller to inhibit axial rearward movement of the associated cam roller when the associated cam roller has been received in the notch. A pressing tool and a jaw set incorporating the aforementioned jaw arm is also disclosed.
