The PREP 3 is torque reactive. This means that the pipe or tube does not have to be fixed to be beveled, making it particularly useful on-site, in
maintenance and repair situations. This is due to the design and strength of the thru shaft systemthat locks to the bore of the pipe.

Features & Advantages
The Jaw system itself consists of 3 equilaterally positioned machined jaw segments, retained and locked on an inner, ‘grooved’ expansion shaft.
These grooves keep the jaws held securely in position, unlike other systems that use a metal or rubber bands for jaw retention. as the expansion nut is is tightened, the jaws expand, locking tightly, and square to the bore of
the pipe.

All units are supplied complete with all gripping segments to cover the full range of the machine. Service tools, drawings, instruction manual
and warranty certificate are also supplied as standard.
Each machine is supplied with a protective metal carrying case.
We strongly recommend the use of a portable filter lubricator with all our pneumatic models.
