SATA, Piston Ring Compressor 4" | 60-175mm Capacity

The SATA 4" Piston Ring Compressor is an essential engine building tool designed to facilitate the smooth installation of pistons into cylinder blocks. With a height of 4 inches and a working capacity of 60mm to 175mm, it provides extended coverage for pistons with multiple ring grooves. Constructed from high-grade heavy spring steel, it ensures uniform compression of even the stiffest rings. The tool utilizes a positive lock ratcheting action for precise control and features a convenient fingertip release mechanism. A safety bead along the lower edge prevents the compressor from slipping into the cylinder bore during use.
