The Mini-Max pneumatic head driver from TRIC Tools fits inside either a 6- or 8-inch PE cap, and is both head driver and pipe puller in one. Taking full advantage of a pulling cable under load, it unleashes stored tension to achieve results. Compact soils, dresser couplings and even ductile iron can be defeated with the right bursting head armed with a loaded cable as ammunition and a rapid-fire hammer as the trigger. The hammer operates efficiently with only 60 to 75 cfm of air at 100 psi. It is easily slipped into place after the PE cap is fused onto the replacement pipe. 888/883-8742; www.trictools.com.
