Your threaded ring gauge (GR) is calibrated with a wear inspection plug gauge (GW) for threaded thread ring gauges.

OSG handles wear inspection screw gauges in standard stock.

In addition, we also accept the service of sending the actual gauge and calibrating it.

Plug gauge is a common name for a plug-shaped cylindrical gauge.

Also known as a plain gauge, it is used to check the accuracy of the hole and the inner diameter and pilot diameter of the internal thread.

Both the street and stop sides are passed, which ensures the accuracy of the hole and the inner diamet

ANSI is a combination of external thread , internal thread and parallel threads with a relatively precise fit in the machine coupling.
The accuracy is similar to G A class, but there is a gap of 0.03 or more, and it is Unified 2A and 2B grade.

What is an NPTF thread?

It is an ANSI standard tapered thread.
Compared to NPT, it has excellent density resistance, and it has a chevron shape that can ensure density resistance without using a sealant.
NPTF external threads can be used not only with NPTF female threads but also with NPSF and NPSI.
Thread angle: 60 degrees
0.5/16 taper per side

It is a screw commonly called a parallel screw for JIS (ISO) pipes, and it is a parallel screw for mechanical coupling of the current JIS standard. （JIS B 0202）
・Both the male and female threads are represented by G.
・ It is the G thread that fits into the G internal screw.
・Thread angle is 55 degrees
・The name is expressed in inches, and th
