6 "IPS to 18" OD (160mm - 450mm).

Rugged and reliable, the Pit Bull® 618 was built for workplaces where wheeled or tracked vehicles are not needed. Ready for the trench or any other tight space, the Pit Bull® 618 is as tough as it sounds. The machine is compact and retains many of McElroy's popular features, including the patented Center Line Guide system for even distribution of force around the joints.
