Cleveland, OH-based Brennan Industries Inc. has a line of gap gages designed to assure that instrumentation tube fittings have been sufficiently pulled up. Brennan says the gages are useful for tightening fittings in hard-to-reach locations and where insufficient make-up could result in dangerous or expensive consequences.

After installation of a tube fitting and before pressurization of the system, the gage is inserted between the fitting nut and the body hex. If the gage will not fit in the gap, the nut has been properly made up and no further tightening is necessary. If the gage can be placed between the nut and hex, the assembly must be repeated. The gages have both ÒGoÓ and ÒNo GoÓ ends and should only be used for initial make-up, not re-make assemblies. The NGG Series carbon steel gages are range from 5/8- to 2-in. sizes.
