The Nitrous Express Super Shark nitrous solenoid features a .178 inch orifice and is intended for use in nitrous systems. It is configured with a side inlet threaded 1/4 in NPT and a bottom exit threaded 1/8 in NPT to route flow through the valve, and the defined orifice size provides a clear flow reference when planning plumbing and fittings for a nitrous installation.
