Industrial F3LP-7A220-AC Air Gage Bore Setting Ring

Industrial F3LP-7A220-AC Air Gage Bore Setting Ring is a precision master ring used to establish a reference bore size in air gage measurement systems. As a setting ring, it provides a predetermined diameter that allows air gage components—such as air plugs or air rings—to be zeroed or calibrated for repeatable bore measurements. In a typical bore-gage setup, you would pair this ring with an air gage unit to verify cylindrical bore dimensions and ensure consistent measurement baselines across parts and production runs. The F3LP-7A220-AC designation identifies a specific size in the catalog; exact dimensions and tolerances are defined by the supplier’s specification sheet. Common applications include calibration and setup of air-driven bore gages in machining shops, inspection rooms, and metrology labs, where establishing a stable reference size reduces measurement drift and speeds go/no-go assessment of cylindrical components. This ring is used as part of a larger metrology workflow to minimize variability when checking bore diameters in production environments. When selecting a setting ring, users typically consider the anticipated bore size, desired tolerance, and compatibility with their air gaging system; procurement should be guided by the manufacturer's published specs for F3LP-7A220-AC.
