You can consider them as piston ring squeezers to squeeze your piston rings during installation. It helps you to line your piston and install it in the cylinder without hassles. 

You can find two types of piston ring compressors in the market. One is the expander ring compressor kit that you use to compress your rings before installation. 

Another one is the tapered one that you gradually tighten to narrow down your piston rings.
