Patent 7188508 was granted and assigned to Emerson Electric on March, 2007 by the United States Patent and Trademark Office.
A jaw arm for a compression tool has a jaw recess at one end and a jaw insert is supported in the recess for pivotal displacement relative thereto about an insert axis. A compression tool comprises a pair of parallel spaced apart side plates, and a pair of the jaw arms pivotally mounted between the plates. The pivotal inserts are self-aligning with respect to a pipe and coupling to be crimped together and provide for use of the compression tool in areas with limited accessibility.
