Industrial Go/No-Go gauge for verifying bore diameters of 1.438, 1.4426, and 1.3900. This tool enables quick quality checks in pipe machinery and related manufacturing, confirming whether a part’s diameter is within tolerance. The GO size corresponds to the minimum acceptable bore, while the NOGO size ensures the bore does not exceed the maximum tolerance. It is commonly used in machining and assembly of pipes, tubes, fittings, and other machined components where precise bore dimensions underpin performance and interchangeability.
