GT30 Midland Gas Test Gauge, 0–30 PSI, 3/4 in FPT

The Midland GT30 gas test gauge provides a 0–30 PSI measuring range with a 3/4-inch female pipe-thread connection.

Compared with the GT15, this model doubles the upper end of the test range to 30 PSI. That makes pressure range the primary selection difference between the two Midland gas-test gauges.

Choose GT30 when the test procedure requires the broader 0–30 PSI scale and the installation accepts a 3/4-inch FPT connection. Confirm both points before ordering.
