The McElroy PitBull 412 hydraulic fusion machines butt fuses a range of pipe sizes from 4" IPS - 12" DIPS pipe (110mm - 340mm) above or in the trench. The robust machine has two fixed and movable clamping jaws resulting in perfect pipe alignment for faster fusions and greater quality. The machine is modularized for portability and ease of use in the trench. The same hydraulic power unit (HPU) is used with all of the PitBull machines affording greater flexibility. Mitered inserts are available for fabricating ells in the shop or at the job site. Attach an optional McElroy DataLogger to record critical joining parameters.
