Ralston QTHA [QTHA-2FSA] 1/4" Female NPT x Female Quick-Test Gauge Adapter, Stainless Steel

The Ralston QTHA-2FSA 1/4" Female NPT x Female Quick-test Gauge Adapter connects a pressure gauge or other device with male NPT connections to a hand pump or nitrogen calibration device. It can be installed with thread tape once onto any male NPT pressure gauge; the Quick-test connection can then be used to quickly connect or disconnect from any hand pump, nitrogen calibration device or other Quick-test adapter. The adapter saves the threads on a pressure gauge by not needing to make and remake the connection with thread sealant.
