The OEMTOOLS Piston Ring Compressor is self-locking with double tension band and heavy duty pawl. It is designed to handle most types of rings in the majority of passenger cars, including those that are channeled and segmented. It has a beaded edge so that the compressor can’t enter a cylinder with a piston. The 1/2″ wide spring bands equalize the tension over the entire belt width so that the spring assembly may be compressed into the groove until it’s flush with the piston.
