Press tool jaws are a critical part of any press-fit installation because the jaw profile must match the fitting system being used. The correct jaw allows the press tool to apply a controlled, repeatable force around the fitting and create the joint specified by the manufacturer.
Different press systems can use different profiles and size ranges, so jaws should never be selected by pipe diameter alone. Installers should confirm the fitting brand or system, required jaw profile, tool compatibility and condition of the jaw before starting work.
Jaws should be kept clean, inspected regularly and serviced or replaced in line with the manufacturer’s guidance. Worn, damaged or incorrect jaws can compromise joint quality even when the press tool itself is operating correctly.
Explore the jaw options below and pair them with a compatible press tool, fittings and pipe preparation equipment for reliable site installation. You may also find the related press tool deals and composite press fittings useful when completing the system.
