NV12R has a 1 inch NPT Inlet and 1 inch Hose 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.
