Pit Bull® 618

200mm - 450mm (8" - 18")

The Pit Bull 618 is used for special applications where space is limited but the power of hydraulic facing is advantageous. The Pit Bull 618 offers the flexibility to fuse pipes and fittings from 200 to 450mm (8”-18”).

The powerful hydraulic facer allows operators to face and prepare the pipe for fusion with speed and efficiency. Pit Bull 618 machines incorporate a 4-jaw carriage that can be converted to a 3-jaw carriage providing an even more compact fusion unit. The flexibility allows operators to configure the machine based on jobsite needs.

The Pit Bull 618 provides the rugged reliability you expect from McElroy equipment, and is engineered with the polypropylene fusion industry in mind.
