Cast Steel Universal Air Hose Coupling, 3/4 Inch Male NPT

Cast steel construction and a rubber seal make it well suited for air and water service. The pressure rating is 150 PSI at 70 degrees F, and it holds up across a temperature range of negative 20 to 160 degrees F. One hard limit to know up front: steam service is completely off the table. Never run steam through any Universal coupling in this line, regardless of pressure or temperature.

Male 3/4 inch NPT is what it’s built with, so it’s the male threaded end in that size.
