NV23R has a 1 inch Hose Inlet and -10AN Male Thread Outlet. Remote included. Perhaps the ultimate fuel valve – the NV™ Nitro Valve. Built tough from aircraft aluminum then anodized, the NV™ petcock includes many outstanding features such as spring- loaded detents for positive on/off positioning and stainless steel components. This valve was designed for nitromethane systems and flows at 9 gallons per minute. May also be used for gasoline and methanol. (Part number shown in picture is NV12, all other NV™ valves may look different than pictured)
