OEMTOOLS Piston Ring Compressor

The OEMTOOLS Piston Ring Compressor is designed to handle most types of rings in the majority of passenger cars, including those that are channeled and segmented. Features a beaded edge so the compressor can't enter a cylinder with piston. The 1/2" wide spring bands equalize the tension over the entire belt width so that the spring assemble may be compressed into the groove until it's flush with the piston.
