1 7-56 Dimensionair Air Gages Air Plugs Features Calibrated I.D. tooling for the Dimensionair Air Gaging Systems Tooling is interchangeable without adjusting system magnification. Federal Air Plugs have large clearance (see table below), allowing easy entrance into the hole being measured and greater measuring range. Long life - wide clearance and hard chrome (optional) body extends useful life of the Air Plug. Deep, recessed jets - Air jets are recessed into the plug body which protects them from damage. Large jet size eliminates clogging from dirt and oils.. Plug identification Air Plugs are marked with an identification number which identifies its size, number of jets, plug style, and the Dimensionair Model the plug should be used with. For example: 0-T is the identification number of an Air Plug for a or a standard magnification 832 Dimensionair (0), throughhole style with two jets (-T2), and 25mm/1.000 nominal size (-1.000). The number (50) which identifies the Dimensionair intended is marked on the plug and also appears on the dial of the Dimensionair to help in matching the tooling to its corresponding Dimensionair Model.
