NV14 has a 1 inch NPT Inlet and -12AN Male Thread Outlet. 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.
