Powerbuilt Piston Ring Compressor Kits

Keep piston rings in place during reassembly with a Powerbuilt piston ring compressor kit. Innovative piston ring bands can be tightened to fit any piston from 2 7/8 in. (73mm) to 4 3/8 in. (111mm) in diameter. Just attach the ratcheting pliers to the band and compress in small increments until the proper size is reached. The band will hold the rings securely until the piston is reinstalled. Instructions are permanently fastened to the inside of the heavy-duty storage case. These tools are precision-built to meet or exceed ANSI standards
