Water Pressure Gauge Flow Test Meters 2.5" Female Threaded Measurement Gauges for Pipe Threads and Pipes (Premium 2.5" Water Pressure Test Meter)

Does not work for me. The tread seems to be 3/4:" FPT (Female Pipe Tape) with a rubber gasket like something that might screw onto a standard USA 3/4" hose bib (i.e., garden faucet)---but the threads are all wrong for that. Item description mentions garden hoses but this can't possibly work for same. Going to send it back.
