Square the ring before checking end gap
This adjustable piston ring squaring tool positions a ring squarely inside the cylinder bore before you measure its end gap. It covers 2-5 in bores. The three slotted arms have hand-adjusted contact points to suit the bore diameter.

End gap checks
Use a separate feeler gauge to measure the gap once the ring sits square in the bore. Follow the ring and engine manufacturer's instructions for measurement depth and the required gap. The bore range describes the tool's adjustment range; it does not set the correct end gap for your engine.
A ring expander spreads a ring for fitting it onto a piston, while a ring compressor holds the rings inward during piston installation. A ring filer removes material to increase end gap. This tool handles the squaring step during gap measurement.
