Typical Applications
Used to turn a 1/4 in. tube line 90 degrees into a 1/2 in. female-threaded port, accepting a male pipe nipple, valve, or gauge stem. The forged-brass body and 300 psi rating suit compressed air, hydraulic oil, fuel, and water lines where the run changes direction and needs a larger female NPT connection.
