Phantom Thread plug gauge ASME B1.20.1 NPT 1/8″

The Phantom Thread Gauge for NPT threads is designed for precision inspection of tapered internal threads. You check the insertion depth using the measuring surface on the pin; if it falls within the tolerance, the thread is dimensionally accurate. This allows you to perform a quick pass/fail check. Upon request, Phantom gauges are also available with a certificate for your quality reports. Essential for a leak-tight connection.
