Scuba Pressure Gauge to 1/4" NPT

            Scuba Pressure Gauge to ¼’’ NPT      

This is a pretty cool one.  This takes a regular scuba pressure gauge and converts it to male ¼” npt.  All you have to do is take your pressure gauge off the hose, screw your pressure gauge in the one side (spool included) and then hook up to any ¼” npt line.
