PI-GAGES FOR I.D. AND O.D.
Starrett PI-Gages protect product quality by maintaining critical diameter
tolerances of plastic lids and containers where shrinkage, temperature and mold
affect parts manufacturing. The diameter of these parts is critical to the sealing
integrity between lids and containers.
Special GaGinG We have developed a wide variety of hand held and fixture gages for many

related applications. Starrett PI-Gages measure most diameters accurately to
within ±.001.
Designed to measure any flexible circular part, variations of these gages have
been in use for over 25 years, and have become the standard of the industry.

This gage ensures container quality requirements with an easy-to-use
gage system. With either electronic indicators (and data collection), or dial
indicators, this gage measures most product diameters to ±.001" accuracy.

Each gage from the 2" to 4" range through the 10" to 12" range is
set to zero with the master. Push the button on the indicator to insert
a part and release the button to gage a part within ±.025" diameter
range from the master size. They provide quick changes from size-to-
size, ease of use, and ±.001 accuracy on most diameters will ensure
process control.
