How to Select an Air Plug Gauge
The nominal bore starts the conversation; the drawing completes it. Jet position, land length, grooves, ports, taper, ovality, surface finish and required insertion depth can all change the plug design.

Engineering workflow
- Share the controlled drawing and tolerance.
- Define static, dynamic, taper or multi-level measurement.
- Confirm masters and setting frequency.
- Select channel count and result handling.
- Review air preparation, ergonomics and wear protection.
Worked example
A 20 mm through bore with uninterrupted land and 20 µm tolerance may suit a conventional two-jet comparative plug. A cross-hole at the jet plane or short land can require relocated jets or another method.

- The online selector cannot establish jet diameter, clearance or master values.
- Final selection requires engineering review.
