Sometimes referred to as pipe thread because PVC pipe and schedule 40 pipe are typically threaded in NPT. As its name implies this is a tapered thread so that the outside diameter of the male (ODM) gets smaller towards the end of the fitting and the inside diameter of the female narrows with depth. As the two fittings are threaded together the opposite tapers force thread friction and makes the seal without the use of a gasket. ## Features - UL & CUL listed EX6430. 1/2 " NPT (National National Pipe Thread) American thread fire sprinkler heads - Temperature Rating: 155°F (68°C);Discharge Coefficient: K=5.6(U.S) /80(Metric);Nominal Orifice Size:1/2"(15mm) - Maximum Working Pressure:175psi(12bar); Min.
