The Akerly & Childs Xtreme ring gauge is a precision made essential tool for the engine builder that performs 2 different critical inspections. First it is used to check piston ring roundness whether rings are new or used.

To perform this inspection, place the ring in the gauge and hold it up to a light. If no light shows thru the ring can be put into service. If any light does show thru gently press your
thumb against the ring where the light is coming thru. If light is no longer coming thru the ring then it can be put into service. If you are unable to eliminate the light from showing thru by gently pressing on it with your thumb then the piston ring should not be put into service.

Secondly, placing the ring at the bottom of the gauge, and then using a feeler gauge ring end gap can be checked.
