This set includes seven jaw sizes—1/4", 3/8", 1/2", 5/8", 3/4", 7/8", and 1-1/8"—so you can move from one pipe size to another without interruption. It works with standard electric press tools including PZ-1550, PZ-3240, EB-1550, and widely used models like RP310, RP320-E, RP340, and M18.

Each jaw is made from carburized steel with a hardness of ≥52HRC, delivering precise pressure and torque during every crimp. That means cleaner seals and fewer connection failures, even in high-demand systems like gas lines and radiant heating.

The compact build makes it easier to position the tool in confined areas, whether you're working behind units or inside tight mechanical spaces. The included PE case keeps everything protected, organized, and ready to move between jobs.

Compared to generic jaws, this set focuses on consistency and job-site efficiency—less adjustment, smoother operation, and reliable results across multiple applications.
