Flange spreaders separate flanges safely and easily without hammering. The spreader, which attaches to the flange holes, spreads the flange faces without damaging flange sealing surfaces. The wedge action of the spreader widens the gap between flanges up to 11/4" (32 mm). 100 ft-lbs. of torque applied to the flange spreader yields up to 12,000 lbs. of spreading force.
Hydraulic flange spreaders are available for 2" - 36" (51 - 914 mm) flanges and use a hydraulic pump kit (sold separately) to easily separate flanges.
