SATA, Piston Ring Compressor 3" | Spring Steel Construction

The SATA 3" Piston Ring Compressor is a professional engine tool designed to compress piston rings evenly for smooth installation into the cylinder. Constructed from heavy spring steel, it is stiff enough to compress even the toughest rings without deforming. The tool features a positive lock action with a ratcheting mechanism that ensures precise compression, coupled with an easy fingertip release lever for safety and convenience. A critical design feature is the beaded lower edge, which prevents the compressor from accidentally slipping into the cylinder bore during piston installation.
