Fixed-size air ring gage with two or more opposing jets around the inner bore to measure a part's mean outside diameter — faster and more repeatable than snaps for high-volume work. Precision ground, hand-lapped, and calibrated to a NIST-traceable master plug.
- External diameters, mean OD
- Fixed size — specify nominal OD and tolerance
- High-volume repeatability
