The Pit Bull line of fusion machines is the workhorse of the McElroy fusion machine line with a marked level of endurance and durability. The carriage alone provides all the muscle you need to fuse small- and medium- diameter pipe. The carriage, heater, insulated heater stand and Hydraulic Power Unit (HPU) are separate components that can be situated in various arrangements to allow flexibility in confined environments. All of the McElroy Pit Bull models feature serrated jaws and inserts to keep the pipe from slipping during fusion. Compact and portable, the Pit Bull fusion machine is built specifically for pipe fusion in the trenches, making it the ideal choice for use with HammerHead PortaBurst pipe bursting systems.
