NPT Brass Three-Way Fuel Shut-Off Valve","description":"\u003cp\u003eThe Moeller 033312-10 is a brass three-way shut-off valve built for marine fuel tank plumbing, sized for 3\/8 in. NPT connections. As part of Moeller's Brass Shut-Off valve line, it lets a boat owner isolate or redirect fuel flow at the tank, a common need when servicing a fuel line, switching between fuel sources, or shutting off supply for storage and maintenance. The valve body is solid brass for corrosion resistance and long service life in a marine fuel environment, and its three-way design (three ports) provides flow-direction control that a simple two-way shutoff cannot.\u003c\/p\u003e\u003cp\u003eConnection ports are 3\/8 in. NPT, with an inlet configured as female NPT (FNPT) and an outlet configured as male NPT (MNPT), matching common marine fuel tank and fuel line fittings. The valve is manufactured by Moeller Marine Products, a long-established supplier of marine fuel system components, and is sold as a single unit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Moeller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 033312-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type:\u003c\/strong\u003e Three-Way Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Ports:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/8 in.
